Abstract
Experiments were performed to measure the interlaminar fracture toughness (G{sub IC}) of carbon fiber (CF)/Epoxy and CF/PEEK composite materials using DCB specimens. Results for unidirectional CF/Epoxy showed that no effect of thickness and width of specimens upon G{sub IC} is found if a crack length is sufficiently long. In the case of unidirectional CF/PEEK, the measured G{sub IC} showed 20 times higher than that of unidirectional CF/Epoxy. A comparison of the G{sub IC} for the original surface, the fusion bonded surface with PEEK film, and adhesion surface with Epoxy adhesives demonstrated that the fusion bonding is ideal for assembling thermoplastic composite structures of complicated shape. Additionally, finite element analysis was performed and showed good coincidence with the typical measured data in the tests. Therefore it was concluded that the DCB test under suitable loading conditions is reliable to evaluate the fracture toughness, particularly G{sub IC}, that is one of the fundamental properties of composites. 15 refs., 36 figs., 3 tabs.
