Racecar Features Composite Rear Suspension with PPG Fiber Glass
PPG recently announced that Polystrand Inc. used PPG products to build a race car.
PPG recently announced 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 race car featuring what is reportedly the world’s first thermoplastic composite rear suspension. The GT-Lite was designed by Jonathan Spiegel, senior engineer with Polystrand, who drove the car in a Sports Car Club of America (SCCA) event in Houston, Texas. The vehicle reportedly was built to demonstrate that continuous-fiber-reinforced thermoplastic resin is an excellent material for automotive suspension and structural components.
“There are light-truck and passenger-car suspensions equipped with composite springs, but they have always been made with thermoset resins,” said Spiegel. “We believe our car is the first in the world to employ a thermoplastic resin, which offers distinct advantages over thermoset resin, such as faster production cycle times, higher impact resistance, easier recyclability and no VOC (volatile organic compound) emissions during processing.”
Reportedly 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.
“Aiding customers in the development of groundbreaking technologies allows PPG to add value to its products and strengthen relationships,” said Camilo Serrano, global business manager for direct draw fiber glass products. “We’re dedicated to innovation, both internally and as a strategy for helping customers create new markets for their products.”
In the Houston SCCA race, the Polystrand car was in second place when an electrical failure forced it to withdraw.
