The performance of filled fiber reinforced polymer composites is generally determined on the basis of the interface attraction of filler, fiber, and polymer. In the present investigation, the effects of SiC particles as fillers in glass—epoxy (G—E) composite systems on the mechanical and tribological properties have been discussed. The composites employed in the present study have been fabricated using hand lay-up technique. The mechanical properties such as tensile strength, tensile modulus, elongation at break, flexural strength, and hardness have been investigated in accordance with ASTM standards. From the experimental investigation, it was found that the mechanical properties of the G—E composite increased with the inclusion of SiC filler. The dry slide wear test results of SiC-G—E composite show lower slide wear losses irrespective of the load/sliding velocity when compared to G—E composite. Some of these observations are supplemented by scanning electron microscopic (SEM) observations. Further, wear of the matrix, breakage of reinforcing fibers, matrix debris formation, and interface separation were observed. SEM microphotographs of the tensile fractured samples revealed the typical aspects of the fractured surfaces. The failure modes of the tensile fractured surfaces were evaluated and showed good agreement with the literature.

Fiber reinforced polymer composites are generally known to possess high strength and attractive wear resistance in dry sliding conditions. The behaviour of such composites performing in abrasive wear situations needs a proper understanding. Hence, in the present work of the three-body abrasive wear behaviour of two dimensional stitched carbon fabric, E-glass woven fabric and three dimensional E-glass woven fabric reinforced vinyl ester composites was investigated. Three-body abrasive wear tests were conducted using rubber wheel abrasion tester (RWAT) under different abrading distances at two loads, wherein the wear volume loss were found to increase and that of specific wear rate decrease. The results indicate that the type of fabric in vinyl ester have a significant influence on wear under varied abrading distance/loads. Further, it was found that carbon fabric reinforced vinyl ester composite exhibited lower wear rate compared to E-glass woven fabric reinforced vinyl ester composites. The worn surface features, as examined through scanning electron microscope (SEM), show higher levels of broken glass fiber in two dimensional glass woven fabric reinforced vinyl ester composite compared to carbon fabric and three dimensional glass fabric reinforced vinyl ester composites.

Machining of the composites materials may be was troublesome on do as of those anisotropic also non homogeneous structures from claiming composites what's more of the helter skelter abrasiveness about their reinforcing constituents. In this study of the mechanical properties about e glass/ epoxy composite materials for fillers (SiO2 Also PTFE) need focused on with explore the materials included of the grid assistance moving forward those mechanically operating properties of a composite. Those recently produced composites are described to their mechanical properties in elasticity test eventually tensile strength test and Flexural test. Those effects of Different mechanical characterization tests would account here. Those tests result bring demonstrated that higher the filler material volume rate more excellent those quality to both SiO2 also PTFE loaded glass epoxy composites, SnO2 loaded composite hint at a greater amount manage values over PTFE.
