Within the framework of the Ecoxy project, biofibres and biobased resins are being developed to substitute current resins. Due to dynamic hardeners of these bio resins the covalent crosslinks can change under temperature and pressure. This behaviour allows to form, weld or recycle the manufactured composites at the end of their lifetime.

First bio based epoxy result
Composites out of these biobased resins and biobased flax fibers have been successfully processed using the wet compression moulding process. The process for processing the new materials was optimised on the basis of mould filling studies to achieve a complete infiltration of the fabrics. The wet compression process was monitored with an dielectric in-mould sensor from company Netzsch to optimize the curing conditions. The production was demonstrated on a rear seat back panel, which is used in automobiles.
