摘要：

Almond hulls were used as a raw material to manufacture particleboards without adhesives, in order to give a value added to the residue. This study investigated the effect of the pressing parameters on some physical (hardness) and mechanical properties (modulus of elasticity, modulus of rupture, and internal bond strength) of single layer boards. The mats were consolidated after three cycles of hot pressing at 100 degrees C and under 26 kg/cm(2) of pressure, followed. The experimental panels were tested according to the procedures defined by European Union (EN) Standards. The boards obtained were high density. The results showed that MOR, MOE, IB and hardness improved after the third pressing cycle. Their hardness Brinner was bigger than that of the wood based particleboars. The boards had an average IB value of 1.26 N/mm(2). The bending strength was low due to the very low pressing conditions.
