Flexural influence on screw withdrawal behaviour of selected commercial particleboard

Abstract

A study was conducted to evaluate the influenced of flexural strength toward screw withdrawal (SW) and surface soundness (SS) based on selected commercial particleboard. The SW and SS is an important criteria for utilization of boards in application involving board surface properties and board reaction towards usage of fastener. The material was collected from MIECO Manufacturing Sdn. Bhd. The selected commercial particleboard includes 3 different thickness of board (16mm, 18mm and 25mm) were tested. The particleboard ratio was 60% rubberwood and 40% mixed tropical wood with dimension of 60 cm x 120 cm x thickness of board. This study is to investigate the mechanical properties of board that determined internal bonding, flexural, SW and SS of board. The result shows there is correlation on flexural. Meanwhile for SS, the positive correlation was with value of 0.415 according to Pearson correlation analysis.
