The main groups of plastics thatare used in lignocellulosic-plasticcomposites are semicrystalline plastics such as polyethylene (PE)and polypropylene (PP). Only ther-moplastics that melt at tempera-tures below 200ºC are commonlyused in making the composites because of the limited thermal sta- bility of natural fibres. Currently,PE is the most attractive thermo- plastic in making the natural fibre- plastic composites which are main-
