Abstract
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
GIC was determined in double cantilever beam (DCB) test, before and after gamma irradiation at
various doses. Glass transition temperature, Tg of epoxy matrix was determined from dynamic
mechanical measurements. The delamination surfaces of tested coupons were observed by scanning
electron microscopy. The variations in GIC values were correlated with irradiation doses, Tg values
and the features of delamination microfractographs, as well as with the variation under irradiation
of matrix or fibre/matrix dominated mechanical properties.
