In this paper, we study how the polymer composite materials will experience the impact strength at different combinations of matrix composition in different fiber orientations. The polymer matrix composite laminates were made into specimens of dimensions according to ASTM standards and are experimentally investigated by Izod & Charpy impact tests with and without notching the specimens. In the experimental program the laminates were prepared by matched die mould and filament winding techniques. The laminates were made with GFRP, CFRP, and Bi-directional glass fabrics are used as reinforcement, lapox L-12, Araldite LY 556 as resins and lapox K-6, Araldite HT-972,Aradur 5200 as hardeners. The stacking sequences, of laminates are as follows [0/90/0/90], [+45/-45/+45/-45] and [90/-45/+45/0]
