✦ Synopsis
Akstraet--Studies are made to determine the mode I interlaminar fracture toughness, or critical energy release rate, Gtc of composites using a slender double cantilever beam (DCB) specimen. Fracture analysis has been carried out on DCB specimens made of carbon-fibre/PEEK and carbon-fibre/epoxy composites. The calculated critical load and the corresponding displacement for the measured crack size of DCB specimens using the determined fracture energy, are found to be in good agreement with the published test results.
