Mechanical performance of woven carbon reinforced epoxy composites with varied orientation angle

The mechanical properties of woven carbon fibre reinforced epoxy composites laminated with different orientation angle in stacking sequence were investigated. Woven fabric layers with different linear density carbon tow have been produced on modified rigid rapier sample loom and impregnated with epoxy by hand lay-up technique for composite preparation. Curing of composite was carried out at room temperature for 2 h. Five different laminar composites were prepared with different orientation angles [(0/0/0/0), 0/+30/-30/0, 01+45/-45/0, 01+60/-60/0 and 01+901-90/0]. The mechanical properties like tensile, flexural, and impact test) were analysed in both longitudinal and transverse directions. Physical properties such as density and fibre volume fraction were analysed. While comparing the layers of orientation of woven composites, the results of tensile and flexural showed higher properties in [(0/0/0/0), and 01+90/-90/0] stacking in both directions than others. Impact showed higher properties in 0/+45/-45/0 stacking than others.
