Abstract:

The report is the third in a trilogy on the fracture of fibrous composites prepared. It describes a study of the fracture mechanisms in fibrous composites. The report is divided into 2 sections the first part describes the temperature and strain-rate effects on the crack initiation energy and crack initiation energy and crack propagation energy of a carbon fibre-epoxy resin composite and a glass fibre-epoxy resin composite. The second part describes a study of the fracture mechanisms in a hybrid fibrous composite containing carbon and glass fibres. Author, PL.
