Effect of Micro Powder on Mechanical and Physical Properties of Glass Fiber Reinforced Epoxy Composite

Abstract

Fiber reinforced polymer composite is an important material for structural application. The diversified application of FRP composite has taken center of attraction for interdisciplinary research. However, improvements on mechanical properties of this class of materials are still under research for different applications. In this paper we have modified the epoxy matrix by Al 2 O 3 , SiO 2 and TiO 2 nano particles in glass fiber/epoxy composite to improve the mechanical and physical properties. The composites are fabricated by hand lay-up method. It is observed that mechanical properties like flexural strength, hardness are more in case of SiO 2 modified epoxy composite compare to other nano modifiers, were physical properties like density, water absorption are more in case of TiO 2 modified epoxy composite. This may be because of smaller particle size of silica compare to others.
