Abstract
Carbon fiber was sized by a thermoplastic polymer solution mixed with a compatible amine monomer. The effect of sizing agent on tensile strength was studied by single fiber strength testing. Interfacial properties of re-sized carbon fiber/epoxy composite were investigated, with special emphasis on the improvement in both interfacial shear strength and interfacial fracture toughness. The interfacial fracture toughness of composites was characterized by calculating the effective interphase fracture energy rate through the information obtained from the force-displacement curve in the micro-bond test. Fracture topography of micro-bond specimen was observed to discuss the interfacial fracture mechanism. POLYM. COMPOS., 35:482-488, 2014.
