Abstract
In this study the lamina properties of glass/epoxy, carbon/epoxy and kevlar/epoxy composite along their principal coordinate axes were evaluated by performing tensile test. The laminates were prepared by hand lay-up technique and compressed using a compression molding machine at 70 oc and 80 bar pressure. The test was conducted as per ASTM standard D3039 by affixing strain gauges in the specimen to obtain the longitudinal and transverse strain. The mechanism of failure was also studied by performing fractographic analysis using scanning electron microscope which shows peeled off fiber surfaces in the case of kevlar/epoxy laminate.
