Continuous Fiber Reinforced Thermoplastic Composites

Kubota Research Associates, Inc. has developed a revolutionary new process for manufacturing organic based continuous fiber reinforced thermoplastic composites under National Science Foundation Award (NSF#0512869). The manufacturing process was demonstrated and display samples of the composite, prepreg and process were exhibited jointly with DuPont-Toray Co., LTD at the International Plastic Fair (IPF) in Japan on September 24-28, 2005.

P-Wave™ Pseudo IR Process (Patent Pending)

P-Wave™ Pseudo IR Process provides fast and precisely focused heating through a polymer layer by uniform absorption of controlled infrared energy. P-Wave™ Pseudo IR Process can heat multiple isolated Pseudo layers simultaneously. Conventional heating methods apply a high temperature to heat the surface and slowly heat the entire layer of material.

Components...

• RuBA®-C prepreg material is manufactured by impregnating continuous organic high tenacity fiber, such as Kevlar®, into a thermoplastic resin matrix.
• RuBA®-P Pseudo transducer is manufactured by impregnating an absorber into a thermoplastic resin. RuBA®-P converts infrared energy into heat and bonds to RuBA®-C using minimal heat capacity.
• P-Wave™ 2200H-C is an infrared radiation unit outputting a specific range of infrared radiation that passes through RuBA®-C and is absorbed by RuBA®-P facilitating the bond to manufacture strong, continuous-fiber reinforced thermoplastic composites.

P-Wave™ Pseudo IR Process Continuous Fiber Reinforced Thermoplastic Composite Manufacturing...

RuBA®-C and RuBA®-P are layered on a mold and the

Vacuum bag applies contact force forming the materials to the mold. The P-Wave™ 2200H-C is used to radiate the assembly, emitting selected range of infrared radiation.

The Infrared radiation passes through RuBA®-C and is absorbed by RuBA®-P bonding and forming the composite without damage to the continuous fiber.

The Result...

A New Generation of Continuous Fiber Reinforced Thermoplastic Composites Which Are…

• Lightweight
• High Tenacity
• Shatter Resistant
• Bondable
• Quickly & Easily Manufactured
• Not Damaged in an Autoclave
• Recyclable

P-Wave™ Pseudo Composite Technology to Dramatically Improve Shatter Resistance & Anti-spalling of Carbon Composites!
