Abstract

The results of a study on the time- and temperature-dependent behaviour of unidirectional glass fibre-reinforced epoxy are described and analysed. The fracture parameters examined are the fracture strength, the work of fracture and the apparent fracture toughness. It is shown that the fracture strength decreases with increasing temperature and decreasing loading rate; the work of fracture exhibits a sharp minimum in the vicinity of room temperature, and the fibre pull-out length increases by a factor of 4 at 76K as compared with the room temperature length; the fracture toughness is found to be independent of the crack length and only dependent on the fracture strength; thus its trend with loading rate and temperature follow those of the fracture strength.
