Toho Tenax Europe is manufacturing the assembly carrier for the Porsche GT3 Cup II. It is the first automotive part being produced in serial production with Tenax Part via Preform (PvP) technology in Heinsberg, Germany, supplied directly to the OEM.
Within the Teijin Group, Toho Tenax is expanding its composites businesses by integrating advanced composite technologies to form a dedicated Teijin composites business unit. The Porsche GT3 Cup II was exhibited by Teijin at the JEC World 2017.
The assembly carrier is produced based on a preform made with random fibre spraying, substituting woven fabric preforms. A carbon fibre treated with binder is sprayed, consolidated and trimmed automatically by a robotic system developed at Toho Tenax Europe GmbH.
Compared to the current state of the art process – to use fabric based on carbon fibre being draped manually in the mould – the Tenax PvP process is said to produce preforms automatically without internal cuts and draping effects.
“The homogenous PvP preform leads to a perfect load behaviour of the part,” the company explains. “At the same time, costs are significantly reduced due to the automation of the whole preforming process, providing reduced intermediate steps and adopted quality assurance efforts. The injection is using the HP-RTM technology including an in-mould coating step providing easy to paint surfaces with high quality.”
Toho Tenax is the core company of the Teijin Group's carbon fibres business. The Toho Tenax Group is a leading carbon fibre manufacturer with facilities in Japan, Germany and the USA and a producer of a variety of semi-finished materials and parts based on carbon fibres.
