Bentley Motors Research the Cost & Weight Advantages of Composites

12th March 2012

Composites World reports that luxury automotive manufacturer, Bentley Motors and fabric manufacturer, Sigmatex, have announced that they have recently completed a research and development program partially funded by the Technology Strategy Board under the Advanced Composite Truss Structures (ACTS).

According to the article:


“The project included a study of fabrication costs between composites versus the baseline aluminum construction in an automotive structural element. In the study, a sample “A” pillar node was fabricated using the Bentley automated fiber deposition process, finished by pressing, and by the Sigmatex One Piece 3D weaving process with subsequent resin infusion. In this study, the technically superior composite solution was produced using the 3-D woven preform and the resin infusion process. In reaching this conclusion, the study put a value of weight saving at €5/kg for this automotive application.”

“The study, the companies say, demonstrates that 3-D woven preforms can be cost competitive in low-volume, complex-shape automotive applications. Due to the higher mechanical properties and reduced variability through automated process control, the component fabricated from 3-D fabric would have a lower weight than the automated fiber placement component and a very significant improvement compared to the aluminum part.”
