Hygrothermal Aging and Fracture of Glass Fibre-Epoxy Composites

P. D. Anstice / P. W. R. Beaumont

Fractographic data for composites of unidirectionally aligned glass fibres in epoxy were obtained for two failure parameters: fibre debond length and fibre pull-out length, which are distances over which intact fibres debond and pull out of a cracked matrix under monotic loading. Other data were obtained on fracture, humidity and hygrothermal aging time. Fracture maps were constructed using this data and fracture models were developed which showed the effects of humidity and time upon microscopic variables such as failure strength, stiffness and toughness, and fibre-matrix mismatch strain, and the resultant influence on work of fracture.
