Abstract

Results are presented from a study to assess the effect of the interlayer modulus on the energy release rate and fracture mode ratio in interleaved composite laminates. Two different geometries and material systems are studied. It is found that the fracture mode ratio is a very strong function of the interlayer modulus, and that varying the interlayer modulus can significantly change the percentage of opening mode which occurs for a given remote loading. The significance of these results is addressed with respect to choice of an interleaving system, as well as with respect to methodologies to eliminate computational difficulties associated with the oscillatory stress singularity in non-interleaved composites.
