RecComp: Recycling of composite materials

This technology allows recycled fibrous material to be incorporated into sheet moulding compound.

Recycled materials are obtained from grinding sheet moulding compound (SMC) and dough moulding compound (DMC) materials from in-production waste or end of life cycle waste.

A prototype manufacturing arrangement is available and proof of concept has been established in trials using SMC production equipment.

Key benefits

Moulding techniques produce a significant amount of waste that can be recycled using this technique.

A significant portion of the virgin fibres can be replaced with minimal effects on the mechanical properties or surface finish, if processing conditions are just slightly adjusted.

Recycled materials can be introduced to the production line at the same stage as the virgin glass fibres.

Applications

EU legislation requires a large per cent of end of life vehicle materials to be reused and recycled.

The automotive industry is a heavy user of composite materials, particularly SMCs, for parts such as tailgates, engine covers, grilles and battery casings.

The electrical and construction industries are the other two main users of SMC/DMC materials.
