Abstract
The purpose of this study was to develop effective green insulation boards fabricated from polyurethane (PU) reinforced with Kenaf fibres. Biocomposites having three different weight contents (40/60, 50/50 and 60/40 Kenaf/PU weight %) were manufactured. A fourth type was made from 60/40 NaOH-treated Kenaf/PU weight %. The results show that the elastic properties increased with Kenaf fibre content. The optimal performance was observed at a weight of 50% Kenaf fibres. Furthermore, the minimum water absorption percentage, thickness swelling, and changing in volume were recorded at a weight of 50% kenaf fibres.
