Abstract

This study was carried out to investigate the properties of woodceramics made from woody part of Broussonetia Kazinoki at different impregnation ratios of phenolic resin of 40, 50, 60, 70%. The physical and mechanical properties increased with increasing impregnation ratio. The highest mean values of density, bending strength, Brinell hardness and compressive strength were 0.66 g/$cm^3$, 53 kgf/$cm^2$, 187 kgf/$cm^2$, 126 kgf/$cm^2$, respectively. There were close correlations between density and bending strength, Brinell hardness and compressive strength, and between MOE and MOR.

인피섬유로 한지를 제조하고 남은 닥나무 목질부를 고부가가치화 하기 위하여 닥나무 목질부로 파티클 보드를 제조하고 페놀수지 함침율 변화에 따른 닥나무재료 우드세라믹을 제조하여 물성을 검토하였다. 밀도, 휨강도성능, Brinell 경도, 압축강도 등은 수지함침량이 증가할수록 증가하였으며 밀도와 휨강도성능, 경도, 압축강도간 및 휨탄성계수와 강도간에는 유의성이 인정되는 밀접한 상관관계를 나타내었다.
