Suitability of Ailanthus altissima wood was determined for the manufacture of medium density particleboard. The panels of particleboard were manufactured from the flakes of ailanthus wood at compression ratio 1.1 and 1.2 with board density 733 and 784kg/m3. Physico-mechanical properties of the boards indicated that a quality particleboard can be manufactured from ailanthus wood. At compression ratio 1.1, strength properties i.e. MOR 446kg/cm2, MOE (48348kg/cm2, SWR 155 kg exceeded the minimum standard values by 163%, 71% and 51% respectively. The properties were improved by increasing the CR from 1.1 to 1.2 with parallel increase in board density.
