Racecar Features First-Ever Composite Rear Suspension with PPG Fiber Glass

July 11 2016

PPG informed that Polystrand Inc., a Denver-based manufacturer of thermoplastic composite materials, used TUFROV 4510 and TUFROV 4588 fiber glass roving products by PPG to build a racecar featuring the world’s first thermoplastic composite rear suspension.

The Grand Touring Lite (GT-Lite) racecar was designed by Jonathan Spiegel, senior engineer, Polystrand, who drove the car in a Sports Car Club of America (SCCA) event in Houston. He said the vehicle was built to demonstrate that continuous-fiber-reinforced thermoplastic resin is an excellent material for automotive suspension and structural components.

Spiegel said he specified TUFROV 4510 continuous-strand fiber glass roving as reinforcement for suspension components because its excellent tensile strength, flexural modulus and sizing compatibility provide superior mechanical properties and fatigue performance compared to other fiber glass products on the market.

TUFROV 4588 long-fiber thermoplastic (LFT) reinforcement roving was laminated into hybrid interior sandwich panels, which made the car lighter and safer to drive, and it was used to reinforce the front air splitter, which acts as an aerodynamic aid under the nose of the car.
