ABSTRACT

In this study, the effect of stacking sequence on the flexural and fracture properties of carbon/basalt/epoxy hybrid composites was investigated. Two types of carbon/basalt/epoxy hybridcomposites with a sandwich form were fabricated: basalt skin-carbon core (BSCC) compositesand carbon skin-basalt core (CSBC) composites. Fracture tests were conducted and thefracture surfaces of the carbon/basalt/epoxy hybrid composites were then examined usingscanning electron microscopy (SEM). The results showed that the flexural strength and flexuralmodulus of the CSBC specimen respectively were ~32% and ~245% greater than thoseof the BSCC specimen. However, the interlaminar fracture toughness of the CSBC specimenwas ~10% smaller than that of the BSCC specimen. SEM results on the fracture surfaceshowed that matrix cracking is a dominant fracture mechanism for the CSBC specimenwhile interfacial debonding between fibers and epoxy resin is a dominant fracture processfor the BSCC specimen.
