AGRE-0050 Fibre and Pulp Production from Unconventional Biomass Fibreplastic Blending Trials and Applications 1 June 1992 - 31 May 1993

A number of techniques are used to produce reinforced plastic forms for use as parts of vehicles, containers, furniture, etc. Conventional products are composed of a plastic matrix into which is embedded glass fibre to provide strength, together with an inert filler such as calcium carbonate and various additives which increase cohesion of the final matrix. The purpose of this project was to see if natural plant fibres could be used as substitutes for glass fibre in a specific use - the manufacture of car body parts. The underlying reasons for doing this related both to creating opportunities for farmers to produce non-food crops and to the possibility of making components which are biodegradable when disposed of. The choice of fast growing, nitrogen fixing (leguminous), species (including broom) which grow as weeds throughout the EU enabled low cost production based on short rotation cycles of about three years. Methods were developed for the complete production scheme, from harvesting through decortication, defibrating, web-forming and moulding - followed by product evaluation. Problems were not found in applying these techniques, but more work is required in formulation of the mix to enhance binding between fibres and the matrix.
