Within the framework of the ECOXY project, biofibres and biobased resins are being developed to substitute current resins. Due to the dynamic hardeners of these bio resins, the covalent crosslinks can change under temperature and pressure. This allows the manufactured composites to be formed, welded or recycled at the end of their lifetime.
Composites made of these biobased resins and biobased flax fibres have been successfully processed using the wet compression moulding process. The process was optimised on the basis of mould-filling studies to achieve complete infiltration of the fabrics, and monitored with a dielectric in-mould sensor from Netzsch to optimize curing conditions. The production was demonstrated on a rear seat back panel used in automobiles.
