This research focused on a nanoscale modification of traditional polymeric matrix morphology through particle introduction and subsequent void formation. The main areas of research have been a study of interlayer modification and analyses of continued carbon fiber reinforced polymeric matrix composites at the nanoscale. The results showed improvements in toughness up to a critical threshold, after which, an increase in the concentration and size of nanoparticulate matter and corresponding foams in the matrix deteriorated the fracture toughness properties significantly. Furthermore, nanoscale particles and foams could be used to alter the response of composite materials to a hydrothermal environment. Collectively, we are now establishing, in a reproducible manner, the placement of nanoparticles and foams in interlayer regions.
