Abstract

In a search for an effective use of both scrap wood and porcelain stone scrap, we manufactured threelayer wood-porcelain stone composite board made from both materials. The objective of this study was to improve bending strength properties of the board. Pruned branch with leaf CBL), pruned branch without leaf (B), and root-stump (RS) were prepared as raw material of core layer of the board. In board manufacturing, three types of wood particles were prepared as follows: wood particles processed by using an industrial grinder (IG), by using crushing machine (CM), and wood particles mixed both of IG and CM with weight ratio of 1:1 (IC). The properties of the board were evaluated based on Japanese Industrial Standard. The main results obtained are as follows: the modulus of rupture values of the board manufactured with B and RS were larger than those of BL regardless of processing methods of raw materials. The modulus of elasticity values of the board manufactured with raw materials processed by using CM were smaller than those of processed by using IG and IC regardless of the types of raw materials. The internal bond strength values of composite board manufactured with B and RS were larger than that of standard value of type 18 Particleboard regardless of processing methods of raw materials. The thickness swelling values of all composite boards in this study were smaller than that of type 18 particleboard standard value.
