Abstract
The adhesive strength of a thermophysical bond between two polymers has bee n examined using fracture mechanics. Bimaterial composite specimens were co nstructed by injecting C fiber poly(etheretherketone) (PEEK) into a mold co ntaining one-half of a pre-molded poly(carbonate) (PC) dogbone. The resulti ng specimens were notched at the interface and tested in tension. Adhesion of the two materials was reasonably good, as demonstrated by fracture surfa ces that showed a mixture of PC and C fiber PEEK fragments. Interfacial fra cture energy of the composite was approximately 1.5 kJ/m(2).
