Kubota Research Enhances Composite Impact Resistance

Kubota Research Associates has developed a new method to significantly increase the impact and shatter resistance of composite materials.

The technique works by using a Kubota Research ‘P-Wave’ radiation unit sed to consolidate a ‘P-Wave’ Pseudo-prepreg layer (branded ImpacGard), onto the surface of a reinforced composite. Tests on samples have been conducted at the University of Delaware Center for Composite Materials (UD-CCM) at conditions equivalent to impact speeds of 5 to 9 mph, and results are said to indicate that applying a single layer of Kubota’s ImpacGard increases low velocity impact resistance up to 40% on a 3mm thick M30/8551 carbon/epoxy composite.

Kubota say that ImpacGard has broad applications in the transportation and construction industries to improve advanced materials performance and safety. The P-Wave ImpacGard technology and impact resistance test results will be exhibited in the DuPont-Toray booth at the JEC Composites Show later this month.

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.””
