Natural fibres offer a route to the production of sustainable composites, replacing inorganic and petrochemical based fibres with high-embodied energy. One of the main obstacles to the exploitation of natural fibres is the limited consistency of supply, with batch-to-batch variations in quality. Retting – a process whereby plant stems are left to weather in the fields – has been identified as bein ...
