Toray Composites (America), Inc.



In 1996, the Composites Development Center was set up as a separate operation of Toray Composites (America), Inc. (TCA). TCA produces more than $70 million per year in carbon fiber prepreg, including material for the Boeing 777. TCA is a subsidiary of Toray Industries, Inc., a $9 billion dollar polymer science company. Toray has 32,000 employees worldwide and is the world's largest supplier of carbon fiber.

Spin Test Chamber For Flywheels
The Composites Development Center was established for the express purpose of developing composites manufacturing capability and business in specialized niches. The main focus has been on composite flywheel rotors and Toray is now recognized as being the world's most capable and highest quality manufacturer of composite flywheel rotors. This success is a result of the hiring of professional, experienced personnel, and developing proprietary high-speed filament winding processes.



Toray's processes and methods produce the highest rotor quality with consistent material properties, and cost effective production pricing. We currently manufacture, spin test, and provide design assistance for composite flywheel rotors to five companies.

The Composites Development Center has also been developing other specialized processes in regard to composite rollers and vacuum assisted resin transfer molding.

Our modern facility has 16,000 square feet and includes the following equipment and capabilities:


Filament Wound Flywheel Rotors

  • Multi-axis filament winding machinery with multiple tow winding and automated resin delivery for consistent quality, producing parts up to 4 meters in length. Complete sawing and machining capability.
  • Large programmable oven with 450°F curing capability.
  • Spin test facility capable of 100,000 rpm and ultrasonic inspection of tested rotors.
  • Complete lab with material testing capability, including fiber and void volume fractions, radial tensile/bend strength, etc. Testing and measurement also includes, C-scan, micrographs, Tg, and other tests.
