Warwick University has produced reinforced composites from PP and PET

A UK research project has developed thermoplastic composites for the automotive industry that are strong and easy to recycle. The two-year project led by Warwick University produced composites using PP and PET reinforced with long fibres of glass and carbon.

Dr Mark Pharaoh, leader of the Advanced Polymeric Composite Panels with Low Environmental Impact (Apple) project, told PRW.com: “They’re very tough and because they have a thermoplastic matrix we can shred them and injection mould them – we can still recycle them into relatively high value products.”

The EU end-of-life-vehicles (ELV) directive is putting the automotive industry under pressure to recycle more components. Researchers have moulded automotive parts using a modified vacuum-forming machine and silicone moulding methods. Pharaoh said the processes used standard vacuum forming tooling and had fast cycle times.

He added that vacuum-formed components could be used as semi-structural interior panels with a fabric covering. “We’re looking at the moment at what surface finish we can achieve and how easy to paint components are.”

BI Composites and Security Composites were also involved in the Ј130,000 (E190,000) project, led by the Society of Motor Manufacturers and Traders. Pharaoh said Security Composites was exploring the possibility of using modified manufacturing methods to produce composites for toe protectors in workmen’s protective boots.
