The article presents experimental data on the deformation and strength characteristics of a number of materials reinforced with three-dimensionally woven multilayer glass fabric, which are compared with the corresponding data for traditional glass-reinforced plastics. The accuracy of the formulas proposed [1] is evaluated. The effect of prestressing the warp and weft fibers on the mechanical properties of the material was investigated. The effectiveness of simultaneous prestressing of the warp and weft was evaluated; the magnitude of the optimal force was established.

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.

A statistical analysis has been made of experimental data on the mechanical properties of a glass-reinforced plastic based on T1 glass fabric (Soviet standard GOST 8481-61) and IF-ED-6 epoxy resin (Elektroizolit Plant, tech. spec. TU 26-59) obtained by testing specimens cut from the waste of wound cylindrical shells. The data obtained can be used for estimating the mechanical reliability of products composed of glass-reinforced plastics of this type.

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.

A test program was conducted to develop mechanical strength data on ECDE 7581 glass fabric impregnated with F161 resin. This data is to be used in the new revision of MIL-HDBK-17. The properties determined were tensile, compressive and shear strengths and stiffnesses and Poisson's ratios over the temperature range of -65F to 450F. The results are presented in graphical, tabular, and summary forms.

The effects of the environment on glass fabric reinforced polyester and vinylester composites immersed in distilled water. Tests were performed at a temperature of 70°C with the materials exposed to 100% relative humidity and 25% ultimate tensile strength. Changes in weight, ultimate strength and tensile modulus of different composites were measured over an eight-month period, and the effects of the environment on these parameters were assessed.

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

Structural glass fabric/epoxy laminates were exposed to various periods of immersion in water at room and elevated temperatures and tested after oven drying. Changes in weight, dimensions, and mechanical characteristics with exposure indicated that immersion in hot water had a significant effect on residual weight loss and residual tensile strength. A correlation between these two variables could be derived which is independent of hygrothermal history. The observed deterioration of mechanical properties is attributable mainly to degradative processes to which the glass fiber reinforced plastic laminate is subjected as a result of water penetration processes that are accelerated at elevated temperature.
