EXPERIMENTAL STUDY ON INVESTIGATION OF SIC IN GLASS FIBRE REINFORCED LAP JOINT

Composite materials have been used in several fields like aerospace structures, marine industries, automobiles and armed vehicles. It serves as an appropriate alternative to metals because of its high strength to weight ratio of composites. Most of the current structures use composite materials and its structural design includes the joint strength. Filler materials are the inert materials which are used in glass fiber reinforced polymer (GFRP) composites for modifying the chemical and physical properties of the matrix polymers to reduce material cost. Some of the commonly used fillers are carbon black, calcium carbonate, clay, alumina trihydrate, magnesium hydroxide, bone powder, coconut powder, hematite powder, TiO2, SiO2, ZnS, graphite, etc. In this research, the lap joints fabricate from unidirectional ply and Bidirectional ply of glass fiber reinforced composite with filler materials SiC specimens are subjected to mechanical properties tests.
