Advanced polymer composites have being found
increasing use in a wide variety of load-carrying
structural applications where their specific
strength and stiffness plays a crucial role. One of
the major problems with these materials is their
poor resistance to delamination, particularly the
free-edge and impact-induced delamination. Various
designs to improve delamination resistance resulted
in considerable weight and cost penalties. A novel
delamination suppression concept was proposed
recently based on nanofiber reinforcement of
interfaces between plies in advanced laminated
composites (Dzenis and Reneker, 2001). As one of the
contributors to this research, the author's
study focused on the comprehensive experimental and
theoretical analysis of edge effects in these novel
composites, analysis of rate effects on their
interlaminar fracture, development of methods and
experimental characterization of their
dynamic/impact fracture, and development of new
crack models for thin layers and composite
laminates. This monograph
is the summary of the author s work in this study.
