Kubota Research and DuPont-Toray Develop RUBA-C Thermoplastic Composite

30 September 2005

Kubota Research Associates and DuPont-Toray have discovered a novel manufacturing method for a fibre reinforced thermoplastic composite without degrading the high tenacity fibre.

The new prepreg composite and system for its manufacture, including the advanced material components, were exhibited at the International Plastic Fair (IPF) in Makuhari, Japan, which ran from September 24-28, 2005.

Kubota Research Associates has agreed to license P-Wave Pseudo Process Technology to DuPont-Toray Co., Ltd., and in a joint effort, have successfully developed a new product line using high-tenacity, long fibre materials such as Kevlar to produce a reinforced thermoplastic composite prepreg named RUBA-C.

Kubota Research's P-Wave Pseudo Process Technology uses P-Wave 2200H-C near infrared radiation unit to enable the total manufacturing process for the new thermoplastic composite. The key advantages of this new and unique method are its extremely high tenacity, shatterproof property, ultra light weight and high productivity in manufacturing.

RUBA-C Kevlar reinforced polypropylene and Polyvinyl butyral (PVB) prepreg products and the P-Wave 2200H-C system will be in controlled sales in the 4th quarter of 2005. Kevlar reinforced thermoplastic polyimide and other high performance plastic prepreg products are currently under development, and will be introduced in 2006.

DuPont-Toray and Kubota Research are expediting commercialization of the RUBA-C thermoplastic composite for the manufacture of automotive parts and sports equipment, and are striving to develop other applications to take full advantage of the unique features of this new technology. Ultra light weight thermoplastic composites with high strength and shatter resistance are critical technology needs for automotive manufacturing, which is striving to dramatically reduce the total weight of automobiles, improve gas mileage and reduce emissions without sacrificing strength integrity and safety. Founded in 2000, Kubota Research Associates Inc. is a technology company that has developed and patented P-Wave(TM) technology, which is a new process for joining plastics and manufacturing composites.
