摘要：Poplar lumber (Populus ussuriensis) is impregnated with low molecular weight PF resin, then it is heated and compressed so that the resin is fixed in wood. The wood is called surface compressive wood. This paper measured the index of physical mechanical properties. The result show that the average density of untreated wood is 415kg·m -3 , with the increase of compression set, the density went up clearly. From surface to inner the density is decrease gradually. With the increase of compression set , the compression strength of parallel to grain, bending strength, modulus of elasticity and surface hardness is raised obviously. The color of wood is slightly varied to yellow.
