ABSTRACT: In the present research theoretical method was used to calculated flexural strength of composite material consist of araldite resin CY223 with different weight percentage (20%, 40%, 60%) from Woven roving carbon fibers (0°-45°), where Ansys program version (11) was used to study the effect of different reinforcing under variation loading on flexural strength of composite material. The standard specification (ASTM D790) was used to fabricant the test specimens in Ansys program. The theoretical results shows that high flexural strength value for araldite resin is CY223 after reinforcing with carbon fibers due to high elastic modulus for these fibers and this strength will increase with increasing percentage of fibers.
