Tensile strength and impact toughness of carbon/glass fiber hybrid composites with surface crack

Tensile strength and impact toughness of inter-layer hybrid composites, made of twill woven E-glass fabric and unidirectional carbon fiber in epoxy resin matrix with/without surface crack, were experimentally investigated. Hybrid laminates with eight, ten and twelve layers were prepared by employing the vacuum-assisted resin transfer molding method, while carbon and E-glass layers were stacked in an alternating sequence. Specimens were cut for...
