All-Polyethylene single Component Composite Material

Recyclable lightweight single Component Composite Material developed for Injection-Molded Components

Polyethylene (PE) would be an ideal material for lightweight construction: energy-efficient, can be produced from renewable raw materials, almost residue-free recyclable. However, only PE components that are reinforced as composites for example with carbon or glass fibers are truly mechanically resilient. Scientists at the Fraunhofer IWM, MicroTribology Centrum µTC, together with the Freiburg Materials Research Centre and the polyolefin manufacturer LyondellBasell, have now produced and qualified a sustainable "All-PE composite". The trick is that the reinforcing fiber structures are also made of PE and even form themselves during injection molding.
