HOCKESSIN, DE (SEND2PRESS NEWSWIRE) -- Kubota Research Associates, Inc. headquartered in Hockessin, Delaware, has developed a new method to significantly increase the impact and shatter resistance of composite materials, which is easily applied as a post treatment.

A Kubota Research P-Wave(TM) radiation unit is used to consolidate a P-Wave(TM) Pseudo-prepreg layer, branded ImpacGard(TM), onto the surface of a reinforced composite without degradation associated with excessive heat energy. Demonstration samples were prepared using Kubota Research's patent pending P-Wave(TM) Pseudo Process Technology for advanced composite manufacturing, and an impact resistance evaluation was completed at the University of Delaware Center for Composite Materials (UD-CCM) by researchers M. S. Islam, A. Anwer and B. Gama. The tests were conducted at conditions equivalent to impact speeds of 5 to 9 mph, and results indicate that applying a single layer of Kubota's ImpacGard(TM) increases low velocity impact resistance up to 40% on a 3mm thick M30/8551 carbon/epoxy composite. ImpacGard(TM) has broad applications in the transportation and construction industries to improve advanced materials performance and safety. The P-Wave(TM) ImpacGard(TM) technology and impact resistance test results will be exhibited in the DuPont-Toray booth at the JEC Composites Show 2006 Paris Expo at Porte de Versailles in Paris France, held March 28-30, 2006.

Kubota Research Associates is a new member of the UD-CCM University-Industry Consortium, a globally recognized center of excellence for research and knowledge in the advanced composites industry. Mike Kubota, CEO of Kubota Research Associates said, "We are pleased to have established a working relationship with UD-CCM. Our company along with our global partner DuPont-Toray looks forward to collaborating with UD-CCM to advance the development of P-Wave(TM) technology to bring a new generation of cost-effective advanced composites to the industry."
