Hybrid composites made of carbon and glass woven fabrics under quasi-static loading

Experimental studies are presented on in-plane mechanical properties for two types of hybrid composites made using 8H satin weave T300 carbon fabrics and plain weave E-glass fabrics with epoxy resin. Results are also presented for 8H satin weave T300 carbon/epoxy and plain weave E-glass/epoxy. Studies are carried out under both tensile and compressive in-plane quasi-static loading. It is observed that for hybrid composites, placing glass fabric layers in the exterior and carbon fabric layers in the interior gives higher tensile strength and ultimate tensile strain than placing carbon fabric layers in the exterior and glass fabric layers in the interior. Quantitative data is given for different mechanical properties.

► Tensile strain for hybrid composite is higher than for carbon/epoxy. ► Compressive strain for hybrid composite is higher than for carbon/epoxy. ► Tensile strength for hybrids is higher than that obtained by rule-of-mixtures. ► Compressive strength for hybrids is higher than that obtained by rule-of-mixtures. ► Effect of stacking sequence is presented.
