The driving research questions of this project is: “Is it technically feasible to reuse Glass PP waste as core material of fiber reinforced sandwich panels, and what are technical issues or recommendations for industrialization?”

To answer this research question the following activities have been defined:

  • Analysis of material composition
  • Analysis of shredding technologies
  • Analysis of melting technologies
  • Fabrication of plates

Dutch Composites supplies thermoplastic composite (TPC) materials like tape and panels made of glass fiber reinforced polypropylene (PP). A substantial part of their product range consists of Glass PP products. The core material of their current sandwich panels is made of petrochemical based PP. Therefore, Dutch Composites would like to replace this core with recycled materials. Habro is a supplier of machines for processing TPC and offers technical advice for industrial related questions on processing TPC. Habro supports the project with technical knowledge regarding industrialization. Habro can later also supply industrial machines to the market.
