Effect of Nature Materials Powders on Mechanical and Physical Properties of Glass Fiber / Epoxy Composite

In the present study composites were prepared by Hand lay-up molding. The composites constituents were epoxy resin as the matrix, 6% volume fractions of Glass Fibers (G.F) as reinforcement and 3%, 6% of nature material (Rice Husk Ash, Carrot Powder, and Sawdust) as filler. Density, water absorption, hardness test, flexural strength, shear stress measurements and tests were conducted to reveal their values for each type of composite. True density results had shown an incremental increase with volume fraction increasing and water absorption, hardness, flexural strength and shear stress results had shown an incremental increase with volume fraction increasing with smaller particle size.
