The elastic and strength characteristics of glass-reinforced plastics based on three-dimensional multilayer glass fabrics with high-modulus, hollow and solid glass fibers have been studied. The effectiveness of using high-modulus and hollow fibers in these composites is estimated. The characteristics are calculated from the properties of reinforcement and the matrix and the results are compared with the experimental data.

Off-axis strength tests were conducted on polyester resin laminates reinforced with a balanced plain-weave glass fabric (Tyglass Y449) under static tension and compression and zero-tension stress, zero-compression stress, and fully-reversed stress fatigue. In each case the onset of initial damage was observed as well as rupture of the specimens. The results were compared with a number of well-known failure theories for combined stresses. When the off-axis strengths were compared with curves computed from the failure theories, only those items which had additional constants evaluated from combined stress data appeared to fit the results satisfactorily. Further examination of the failure surfaces for the Tsai and Wu (1971) theory revealed that this fit was only local.

A structural adhesive made from a woven glass material precoated with two-component polyurethane has been perfected. After the coating of the glass fabric, the adhesive is obtained by reacting a premix (dihydroxylated polymer) and a harder (free and blocked diisocyanates) in the presence of a tin catalysts. Values obtained for the strength of the assemblies (3 MPa on shearing) and for the working temperature (as low as 80°C) andt he allowed storage temperature (20°C) and time 91 year) of the adhesive are far better than those initially expected.

The paper deals with the effect of additions of amine terminated butadiene/acrylonitrile (ATBN), carboxy terminated butadiene/acrylonitrile (CTBN) elastomers and bismethacryloxy derivative of diglycidyl ether of bisphenol-A (vinyl ester resin, VE) on the properties of glass fabric reinforced bismaleimide resin composites. Flexural and interlaminar shear strength of the laminates increased in the presence of these elastomers (3 or 5%). Optimum mechanical properties were observed at — 3 % of VE resin. Glass transition temperatures of laminates were determined by dynamic mechanical analysis.

The absorption of water from selected, constant relative humidity atmospheres by glass-filled or reinforced epoxy resin was studied. Four groups of samples were prepared: unfilled epoxy, epoxy filled with glass microspheres, epoxy reinforced with transverse unidirectional glass fabric, and epoxy reinforced with longitudinal unidirectional glass fabric. The absorption and dimensional change rates were measured and formulated in an exponential expression. From the ratio of relative absorption to relative length change, the “hygro-elastic coefficient” was defined.

This report is on the result of flexural fatigue test of honeycomb sandwich structure made of NOMEX honeycomb core, glass fabric, KEVLAR-49 fabric and graphite fiber reinforced plastic facing. The flexural fatigue property was obtained by using the fatigue testing machine of constant load type UF-500, and electro hydraulic testing machine SERVOPET Lab-5. The flexural fatigue of the 1/4 NOMEX core sandwich structure is higher than that of 1/8 NOMEX core sandwich structure. We found that the honeycomb sandwich structure with the facing of graphite reinforced plastics can be used as structure components.

A series of cyclic bending experiments conducted to investigate the frictional effects in bending glass fabric are described. The results indicate that for a given maximum curvature of bending, the coercive couple caused by frictional effects does not change as the bending curvature increases. On the other hand, the hysteresis, which is the coercive couple at zero curvature, increases with increasing maximum curvature of bending. The frictional effects created by interyarn movement are not as important as those caused by interfiber movement.

Glass fabric filled epoxies irradiated at 4.7 K and examined at room temperature by 20 × stereomicroscopy showed an internal flaw structure which increasingly filled the sample as the γ dose was increased. These flaws were determined to be areas where the plastic had debonded from the glass fibers. The extent of this process correlated well with the dose-dependent loss of mechanical strength. Evidence is reported for a similar mechanism in polyimides although visible flaws have not yet been produced. Possible mechanisms for debonding are suggested. New experiments are also suggested to further clarify the failure mechanism.

The results of special field, pilot, and bench scale studies have provided a rational basis for estimating woven fabric filter performance. Measurement of the amount and distribution of residual dust upon cleaned fabrics permits an accurate prediction of intermediate and final filtration parameters for cleaned and uncleaned regions of the fabric during subsequent filtration cycles. The predictive method is based upon the fact that dust dislodgement occurs at the dust/fabric interface in the form of flakes or slabs and not by surface spalla-tion. Since any cleaned filter possesses at least two distinct surfaces (cleaned and uncleaned) having characteristic drag values, the temporal and areal variations in deposit density, cloth velocity, resistance, and dust penetration must be computed on the basis of a parallel flow system. The cleaned area fraction depends upon the type and intensity of the cleaning. Comparison between experimental and predicted performance indicated excellent agreement for glass fabric...

Low-cycle flexural fatigue tests on an epoxyglass-fabric composite were performed at large constant-deflection amplitudes using a modified Tatnall-Krouse plate-bending fatigue-testing machine. Strain vs. cyclesto-failure data were obtained for cyclic speeds of 25, 150 and 425 cpm. The rate of cycling was found to have a strong effect on the low-cycle fatigue life of this composite, but the effect was less pronounced at higher numbers of cycles.

1. To remove metallic powders with particle sizes of from 0.3 to 10μ, it is possible to use filters made from glass fabric mark TSF(a)9P, combined cloth with staple thread and TSSNF. 2. The first two fabrics ensure complete removal from the start of operations, but possess a relatively high hydraulic resistance. 3. Fabric TSSFN provides complete removal after the filling-up period and has a relatively low hydraulic resistance.

This paper describes the influences of the glass content and the environmental temperature on the static behavior of glass fiber reinforced plastics (FRP) subjected to compressive load in the direction perpendicular to the laminated layers. (See Fig. 1 (b))Although several papers were reported associated with the compressive strength of FRP laminated materials, in most case, most of the studies have been confined to the compressive stress in the parallel direction of the laminated layers and few papers are reported regarding the compressive stress in the perpendicular direction (the case shown in Fig. 1 (b)).A method developed for the theoretical analysis of anisotropic laminated materials was applied to the latter.

The changes in tensile properties of nylon, Dacron, Nomex, PBI (polybenzimidazole), X-101 (aromatic polyamide), PRD-14 (polyimide), and glass yarns in vacuum (∼1 × 10−6 torr) at 70°F after seven to ten day and forty-five day vacuum exposures are presented. The changes in tensile properties of fabrics woven from nylon, Dacron, Nomex, PBI, glass and metal yarns in vacuum at 70°F after vacuum exposures of one to sixty-four hours, and the changes in tensile strengths of 9 16 in wide nylon, Dacron and Nomex tapes in vacuum after seven-day exposures are also given. With several notable exceptions, long-term vacuum exposures generally do not have a considerable effect on the tensile properties of polymeric yarns. The tensile modulus of nylon and X-101 yarn, the rupture elongation of Nomex yarn, and the modulus and rupture elongation of Dacron and PRD-14 yarn in vacuum differ by 10 to 25 per cent from their properties in 14-7 psia, 10°F, 65 per cent RH air. The other tensile properties of these yarns and the properties of PBI yarn in vacuum differ from their properties in air by less than 10 per cent and, in most instances, by less than 5 per cent. The tensile strength of glass yarn in vacuum is as much as 39 per cen t greater and the rupture elongation, 25 per cent greater than in air. Vacuum exposures of one to sixty-four hours also appear to have only a slight effect on the tensile properties of polymeric fabrics. However, glass fabric exhibits up to 45 per cent greater tensile strength in vacuum than in air. The rupture load of 9 16 in wide nylon, Dacron and Nomex tapes is 2 to 7 1 2 per cent greater in vacuum than in air.

This research work aimed to develop smart multifunctional composites via a process for uniformly dispersing carbon nanotubes (CNT) on an orthogonal three-dimensional (3D) woven glass fabric with minimised filtering effect. These smart composites could detect strain under tensile and flexural loading by the piezoresistive response of the infused CNT network. Conventional vacuum assisted resin transfer moulding was modified to control the infusion of 0.25 wt% CNT on the 3D woven glass fabric by varying the vacuum pressure. Results showed that at 101.3 kPa vacuum pressure, the CNT percolated through the thickness of the orthogonal 3D woven glass fabric while being marginally filtered by the fibres and were suitable for sensing tensile strain, whereas at 30.4 kPa, the CNT were deposited only on the surface of the fabric preform without getting filtered and were suitable for sensing flexural strain.

A blowhole is a defect in a soldered joint on a printed circuit assembly which incorporates plated through‐hole circuitry. Blowholes are caused by volatiles being generated in the through‐hole during the soldering process and it is often thought that these volatiles originate from the flux. Examination of the problem shows this not to be the case; the most likely cause is bad drilling of the hole and/or poor plating. The construction of the glass fabric used in laminate manufacture may be a contributory factor to bad drilling. The incidence of blowholes can often be reduced by baking the boards immediately prior to soldering. If this treatment is successful in reducing blowholes, it merely confirms that the problem is inherent in the boards themselves and not in the soldering process.

Scaled Flow Testing has been developed as a practical method to characterise the flow and thickness properties of epoxy B‐stage prepreg. This technique evolved from an analytical model of lamination flow based on parallel plate plastometer concepts modified to account for glass fabric effects. Scaled Flow Testing is designed to measure flow comparable to actual MLB lamination flow, thus it provides beneficial B‐stage theology, encapsulating, and pressed thickness data.

At the outset it was observed that the flexibility of phenyl methyl silicone varnished glass fabric was very variable. One. lot of the material was found to have satisfactory flexibility, while the next lot might be otherwise, in that it is “too stiff”, thus making it extremely difficult, if not impossible, to work or pull the material into position without mechanically damaging the varnish film, thereby making the material practically useless. It was soon recognized that if the phenyl methyl silicone varnish film could be plasticized this should be the answer to the problem of non-flexibility, providing there was no substantial sacrifice in the inherent properties of the phenyl methyl silicone resin.

This installation, the only application of a baghouse in oxygen-lanced open hearth fume cleaning in the United States, is considered a success. After the equivalent of 10 months continuous service, less than two percent of the 800 bags have been replaced because of possible wear. Operating experience, compared to the electrostatic precipitators in another open hearth shop at the Sparrows Point plant, shows that power cost is no more than if a precipitator had been installed, and operating and maintenance expenditures are markedly less. Outlet dust loading has been measured at 0.0007 grains per cubic foot. The relationship of gas volume to pressure drop differs by less than 10 percent from the prediction based on a pilot scale study. It is our opinion that this baghouse is properly applied to the cleaning of waste gases from a single oxygen-lanced open hearth furnace.

The development of the polyester nonwoven mat has culminated many years of searching for a high performance backing suitable for flexible electrical insulation. With the use of polyester fibers, a backing superior to cotton in moisture and thermal resistance was possible. The polyester nonwoven mat also overcame the deficiencies of glass fabric in conformability and retention of dielectric strength after crease. These desirable characteristics have given the insulation systems based on polyester nonwoven mat a major position in today's insulation market.

ASME International Mechanical Engineering Congress and Exposition (IMECE2014) -- NOV 14-20, 2014 -- Montreal, CANADA WOS: 000375503500019 In this paper we compare two manufacturing techniques namely vacuum infusion and compression molding, used in manufacturing S2 glass fabric/epoxy composites for high-speed impact applications. Even though compression molding and vacuum infusion are two widely used manufacturing techniques, the resulting product may be very, different. Compression molding has the advantage of achieving a much higher fiber density for the same thickness. With a higher fiber density, the composites made by compression molding have better mechanical properties than a composite made by vacuum infusion. However, vacuum infusion is faster and more. economical. The mechanical performance of the composites manufactured by these two processes are compared by performing tensile tests and high speed impact tests for the' determination of the limit speed V-50. For the same number of plies, preliminary results for compression molded specimens indiCate a 50% increase in stiffness and a 40% increase in strength. Also, for panels of the same thickness, the V-50 was higher for compression molding specimens. ASME
