Abstract

The objective of this research is to evaluate the characteristic of  composite board made from coconut fibre, recycled polypropylene (RPP), and bamboo matting layers. The board samples target density was 0,70 g/cm3. The board construction type was core type composite board (three layers).  Coconut fiber and RPP were used as core, and bamboo matting was used as face and back layers. RPP was used 50% based on coconut fiber oven dry weight. The bamboo sheet wide is 1 cm and 2 cm, with and without bark. The bamboo matting layers were used in slope (45˚) and perpendicular (0/90˚) orientation to length of the board. The research results showed that utilization of bamboo matting layers increase the mechanical properties of board. All of composite board made from coir, RPP, and bamboo matting layers fulfill  the JIS A 5908 standard in density, thickness swelling after 24 hours of water immersions, and screw holding power. Only composite boards with bamboo matting layers with bark, sheet wide 1 cm, and perpendicular orientation to length of the board fulfill JIS A 5908 1994 standard for veneered particleboard in MOE.  However, application of bamboo matting layers without bark is adviced better because more efficient in the raw material using.   Keywords:               Composites board, coconut fiber, recycled polyprophylene, bamboo matting layers

Abstract

Agricultural fibers are currently used as a substituted resource to wood-based products. One of agricultural fibers that has been developed and become a resource for panel products is coir (coconut fiber). The purpose of this study is to evaluate the quality of veneered composite board made of coir and recycled polyethylene (RPE). The target density of board samples was 0.7 g/cm3. The board construction type is core type composite board (three layers). Veneers from Meranti (Shorea sp.) were used as face and back layers and coir was in the core layer. RPE composition was 50% based on coir particle and veneers oven dry weights. Recycled plastics were placed in three layers, 30% on the face and back layers, and 70% in the core layer. The coir sizes were under 1 cm, 1 cm, 5 cm, 10 cm, and 10 cm up (along coir size). The composite board samples were tested by JIS A 5908 – 1994. Each parameter was measured in three replications. The research results obtained are as follows : (1) Veneered composite boards made of coir and RPE fulfill the JIS A 5908 standard in term of density, thickness swelling after 2 and 24 hours of water immersions, modulus of elasticity, modulus of rupture and internal bond, and (2) The coir size did not significantly affect the properties of composite board. Keywords: veneered composite board, coir size, recycled polyethylene
