PROPERTIES OF POLYSTYRENE RESIN REINFORCED BY CARBON FIBERS

Mechanical properties of the composite material based on polystyrene resin were investigated. Polystyrene resin was reinforced with (0, 15, 30, 45 and 60% by weight wt) carbon fibers. The tensile and impact properties of composites were determined by the tensile and impact tests. The maximum impact strength is (183Kj/m2 ) at the weight fraction of (60 % wt) of fibers, comparison with (8 Kj/m2 ) for virgin polystyrene material ,and the maximum tensile strength is (383Mpa) at the weight fraction of (60 % wt) of fibers , comparison with (37Mpa) for virgin polystyrene material.
