KARAKTERISTIK PAPAN SANDWICH DENGAN INTI PAPAN PARTIKEL
Main Article Content
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 bamboojabon 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.
