Abstract : The focus of our research efforts is on marine composite structures; particularly lightweight glass/carbon polymeric based composites, and innovative concepts for the mitigation of blast, shock and impact effects. Technical approach included researching low-cost fire resistant nanoclay and exfoliated graphite platelet reinforced glass and carbon polymeric based composites with fly ash and 3-D fiber reinforced foams; investigating their response to low-velocity impact, ballistic, shock and blast loads; dynamic mechanical analysis for modulus, damping, creep and stress relaxation; developing constitutive models and computer simulations; and evaluating their radar-absorbing and EM-shielding characteristics for improved stealth and safety. Research conducted under this ONR award would also impact the development of composite materials technology for the nation's critical infrastructure; body and modular armor designs for military and civilian vehicles; homeland security; JIEDDO (Joint Improvised Explosive Device Defeat Organization) and DTRA (Defense Threat Reduction Agency).
