KARAKTERISTIK PAPAN SANDWICH DENGAN INTI PAPAN PARTIKEL

Abstract

Bamboo has been recoqnized as wood substitute materials by convertting them into engineered bamboo products. To increase bamboo utilization efficiency, the waste generated from bamboo processing can be used further as raw materials for particleboard manufacture. Besides to get relatively thick and strong material, the bamboo particleboard can be used as a core layer for sandwich panel. The objective of this research was to determine characteristics of sandwich panel with particleboard as the core layer. There were four types of particleboard used as the core layer of sandwich panel i.e bamboo particleboard with density of 0.45 g/cm3 (A1) and 0.55 g/cm3 (A2), and the mixture of bamboo- jabon particleboards with density of 0.45 g/cm3 (A3) and 0.55 g/cm3 (A4). There were three types of outer layer of sandwich panel i.e. bamboo strips (B1), jabon plywood (B2), and mahoni plywood (B3). Sandwich panels were produced using urea formaldehyde adhesive. The results showed that bamboo-jabon particleboard used as core layer produced stronger sandwich panels than those using only bamboo particleboards. Bamboo strips as the outer layer produced stronger sandwich panels than those of using mahoni and jabon plywood. All sandwich panels produced in this research conform to both the Indonesian Standard and the Japanese Standard requirements for particleboard with veneer overlay. Keywords:
