Scott Bader has collaborated with Shape Corp to create a curved, multi-hollow pultruded carbon fibre bumper beam for the 2020 Chevrolet Corvette Stingray. It uses Scott Bader’s Crestapol urethane acrylate resins.

These resins were chosen because of their strength, toughness and lightweight properties, as well as their ability to bond with carbon fibres. The resulting lightweight carbon fibre component helps protect the rear and expanded boot of the Corvette.
The company says it is the first time it has made a pultruded part within an automotive application. Its technical team started working with engineers from Shape on the project back in July 2016.
‘The attribute that we like the most about the Crestapol resin is the ability to withstand the temperatures of the E-coat paint process,’ said Toby Jacobson, plastic materials & process manager in Shape’s advanced product development group. ‘This part is assembled in body, so the part gets dipped and exposed to elevated temperatures. The Crestapol resin provided a solution against other alternatives without compromising performance or process speeds.’
