Abstract:

Hygrothermal aging effects and the micromechanisms of crack extension in glass fibre and carbon fibre composites are described. A new collection of failure data based on direct observation of fibres debonding, breaking and pulling out of a cracked epoxy matrix is presented. The data are summarised in cumulative probability diagrams which provide a convenient means for the comparison of fracture behaviour of composite systems. These diagrams also demonstrate the effects of changes in environment and time in a given experiment in a manner useful for the failure analysis of a fibrous composite. Author
