AIMPLAS· Technological Institute of Plastics

AIMPLAS recently reported that it has made progress in regards to the EU-funded RECOTRANS project, which focuses on integrating unconventional manufacturing technologies to obtain cost-effective recyclable multi-material composites suitable for the transport sector at high production rates.

In particular, new thermoplastic composites have been developed through the integration of microwaves and laser welding. It has been demonstrated that microwaves can be used to optimize the curing process of composites in resin transfer moulding (RTM) and pultrusion, which reduces the energy consumed, shortens manufacturing times and helps produce better quality parts.

It has also been shown that laser technology can be used to obtain stable joints between the composite and metal, thus making it possible to eliminate riveted joints, which typically increase structural weight. Finally, studies were carried out on the recyclability of the thermoplastic composite by using it to manufacture a new part.

AIMPLAS says these results were validated through the manufacture of three life-size demonstration samples using various either carbon or glass fiber reinforcement and a thermoplastic acrylic resin, and one demo sample from the recycling material:

  • A glass fiber-reinforced thermoplastic rear suspension system for a truck cab, manufactured by integrating microwaves into the RTM process; the composite-metal joint employed laser welding.
  • Carbon fiber-reinforced thermoplastic automotive door panel, manufactured via microwave integration with C-RTM.
  • Glass fiber-reinforced thermoplastic interior panel for the rail industry manufactured by using microwaves in the pultrusion process.

The joint between the composite and metal parts was made using laser welding. In addition, the recyclability of the materials was validated by manufacturing a demo sample of a car door handle made of 50% recycled material.
