PENGARUH KOMPOSISI FACE-CORE TERHADAP SIFAT FISIK DAN MEKANIS ORIENTED STRAND BOARD DARI BAMBU DAN ECENG GONDOK
Abstract: The effect of
particle composition made of bamboo and water hyacinth on the dimensional
stability and mechanical properties of resulted oriented strand boards (OSB)
were investigated. Three layered boards were made from bamboo and water
hyacinth in which bamboo strand was used as face/back layer and water hyacinth
strand was used as core layer. The boards were manufactured using three levels
of bamboo and water hyacinth compositions (50:50, 60:40 and 70:30) with 6 %
isocyanate based on the strand oven dry weight. The results showed that
dimensional stability of the OSB decreased with the increase of composition of
water hyacinth strand on core layer. A higher composition of bamboo strand as
face/back layer compared to water hyacinth strand resulted in increased modulus
of elasticity and internal bond strength, but decreased the modulus of rupture.
The bamboo and water hyacinth composition of 70:30 compositions showed better
properties than other compositions.
