Three different types of composite panels, representing different uses, were made using Poplar （Populus tomentosa Carr. triploid clone） and fiberglass as the primary raw materials and PF resin as the adhesive. Compared with common particleboard made with Poplar and PF resin, the physical and mechanical properties results indicated that the density （ρ）, modulus of rupture （MOR）, and modulus of elasticity （MOE） of the panels all improved. However, moisture content （MC） and internal bond （IB） strength both dropped slightly, while thickness swell （TS） was mixed with some specimens having results above the standard and others below.
