Abstract

In this study, a combination of “Cordia Dichotoma” natural fiber and “granite powder” as filler has been reinforced into epoxy resin making a hybrid composite. In this study, unused industrial waste obtained from the granite polishing industry, known as granite powder (GP) is being utilized for its usefulness as a reinforcement in polymer composite. Hybrid composite was prepared by reinforcing a constant Cordia Dichotoma fiber content of 20 wt. % and varying the granite powder weight (wt. %) percentages (0, 5, 10, 15 and 20) into epoxy matrix. Mechanical properties (tensile, flexural and impact) of hybrid composites were investigated. Following the results obtained, granite powder could be evidenced as a good filler material for the betterment of composite’s mechanical properties. Also, the ability of this filler material is proved in decreasing water absorption and chemical resistance. SEM morphology was performed to investigate the bonding and distribution of granite powder within the Cordia Dichotoma reinforced composite material. Besides, presence of chemical functional groups in the composite was traced by Infra-Red Spectroscopy. Also, Thermo-Gravimetric Analysis (TGA) was carried out and the composite was found to be thermally stable up to 455°C.

Abstract

Usage of composites with natural fiber reinforcement is drastically increasing in recent times because of their low density, biodegradable nature, and low cost. However, natural fibers have certain core problems such as poor adhesion between the fiber and matrix and a relatively high degree of moisture absorption. Alkaline treatment of natural fibers is aimed at improving the adhesive strength so that effective stress transferability takes place in the composite. In the present work, Cordia-Dichotoma fibers were treated with sodium hydroxide (NaOH) and composites were prepared with different weight ratios of these fibers reinforced with epoxy. The prepared composites were tested for their tensile and flexural strengths (mechanical properties). Besides, for a comprehensive material characterization, IR spectroscopy (FT-IR), scanning electron microscope, and thermogravimetric analysis were carried out. This work investigates the influence of aforementioned NaOH treatment on thermal, mechanical, and morphological properties of the composite material.

Abstract

The present investigation considers an experimental study of wear analysis of Al-6061 HMMC with SiCp & Graphitep as a reinforcement & optimization of wear testing parameters based on the Taguchi technique coupled with Linear Regression analysis. A Linear Regression Equation obtained from regression analysis is used as a confirmation test, for the optimum testing parameters that are obtained to get the minimum wear rate and maximum Co-efficient of Friction of Al-6061 HMMC. The wear rate experiments are carried out by utilizing the combinations of tribological testing parameters based on the L9 Taguchi OA with four testing parameters of namely applied load, Speed, Track diameter and % of reinforcement. The three materials, Al-6061 HMMC are developed by reinforcing Al-6061 aluminium alloy with different (3, 5 & 7) % of weight fraction (SiCp+Graphitep), particulates of size (p+Graphitep). A confirmation test is carried out to verify the results obtained through the optimization technique. In addition to above tests, Scanning Electron Microscopy (SEM) analysis, Elemental Characterization can be achieved by using of EDAX (Energy Dispersive X-ray Spectroscope), Surface Roughness is performed on the specimens to study the uniform dispersion of particulate matter, along with hardness test.

Abstract

Aluminum amalgam MMCs are ahead of time abundant acknowledgment for vehicle, modern, and aviation application due to their low thickness, high and great basic quality inflexibility. In the present work, an exertion is made to plan and assess the mechanical properties of Al6061-SiC/Graphite half breed composites. The composites were primed by means of stir casting process in which amount of fortification is varied from 2-10% in steps of 3, 5, 7 wt%. The primed composites are characterized as per standards. The scattered Graphite and SiC in Al6061 combination contributed in improving the rigidity of the composites. The SEMs of the examples showed uniform conveyance of the fortification particles in the lattice with no voids.
