Door impact bar test part for the Audi A4 consisting of several layers of woven glass fibre in a polyamide (PA-GF), nylon, matrix. The PA-GF organo is thermoformed into the shape of the mould and then back injection moulded with short fibre PA-GF. The result of a collaboration between Audi AG, Bond Laminates, the Institute for Composite Materials, Jacob Plastics, Lanxess, and KraussMaffei, this is a mass-producible composite suitable for safety-critical automotive applications. It is known as SpriForm and FiberForm.
