Delamination strain energy release rate in carbon fiber/epoxy resin composites
Апстракт
The paper reports on an experimental study of the Mode I interlaminar fracture of unidirectional carbon fibers/epoxy resin composites. Mode I delamination strain energy release rate G(IC) was determined in double cantilever beam (DCB) test, before and after gamma irradiation at various doses. Glass transition temperature, T-g of epoxy matrix was determined from dynamic mechanical measurements. The delamination surfaces of tested coupons were observed by scanning electron microscopy. The variations in G(IC) values were correlated with irradiation doses, T-g values and the features of delamination microfractographs, as well as with the variation under irradiation of matrix or fibre/matrix dominated mechanical properties.
