Evonik explains that the new method combines two traditional production techniques: compression moulding and pultrusion. This combination converts the manufacture of complex geometry composite parts into automated, continuous process and suits for any fiber reinforcing materials, such as basalt, carbon or glass.
According to Evonik, new technology is a response to increasingly growing interest in composite materials in the automotive industry. Plus, the PulPress method reduces costs by up to 60 percent compared to composite parts manufactured using established methods such as resin injection. Up to now, composite components have mostly been used in luxury-class vehicles, as established methods are expensive and complex.
PulPress technology showcased by Evonik at JEC World 2017 in Paris is also of interest to manufacturers outside the automotive industry. It could be applied in aircraft construction for producing large numbers of carry-over parts and lightweight sandwich cores in sports equipment.
