Effect of fibre treatment on the properties of medium density fibreboard made from empty fruit bunches / Zawawi Ibrahim

Natural fibres are widely used in the composite industry because of their availability and desirable properties. Malaysia being one of the largest producers of palm oil in the world generates empty fruit bunch (EFB) that has potential of being used as fibrous raw material in the fibreboard industry....
