Abstract: Wood cellular plywood is a naw kind of composition cellular plywood. The manufacture, of the planet is to arrange the piece veneer which is made into cellular stock with definite sizes and to put veneer on its hoth surface, and then to glue them together. In this paper, the influences on mechanical properties of the planet, such as arrangement of the piece veneer in the core stock and its manufacture technology, are studied. This paper also puts forward a type of the piece veneer arrangement which can be made by mechanization and whole manufacture technology. The main mechanical properties are tested. They areMOR. 14.2~21.6(MPa); MOE. 2~2.7(103MPa);IB. 0.21~0.43(MPa); Density. 0.149~0.206(g/cm3).
