Abstract
The transfer of stress between an embedded fibre and a surrounding matrix, and vice versa, is achieved either by means of a bonding mechanism which can include combinations of chemical bonding, mechanical interlock and slip mechanisms which can include friction between the matrix and the fibre. These two mechanisms can be characterized experimentally for specific fibre-matrix systems. The experimental technique most widely used for the purposes of interface characterization is the pull out test which consists of a single fibre which is embedded in a matrix (Piggot, 1980). This method of fibre-matrix interface characterization is however both time consuming and especially sensitive to the test procedure. The fragmentation test has recently been proposed as a means for studying the interface strength characteristics of composites and their influence of matrix crack development. The test which consists of a single fibre embedded within a large region of a matrix material permits not only the ease of testing but also a clearer study of extended matrix cracking at a cracked fibre region (Chamis, 1974; Busschen, 1991; Sancaktar and Ma, 1992).
