ABSTRACT Oil palm empty fruit bunch (OPEFB) was heat treated at 180°C using a vacuum oven for one hour, extruded and compounded with high-density polyethylene at 10%, 20% and 30% weight fraction. The composites then were injection moulded into dumb-bell shaped specimens. The effect of composition and heat treatment on the thermal properties of composites were investigated using Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC). The tensile and flexural properties were also tested using an Instron Universal Testing Machine. TGA shows an increase in the degradation peak temperature of the heat-treated composites. DSC revealed an increasing trend in the degree of crystallinity (Xc) of the matrix as the heat-treated empty fruit bunch was used as a filler. An increment in the tensile modulus and tensile strain were observed for the treated fibre composites. In addition, the tensile strength value was increased for treated fibre composites with lower fibre loading.

注塑热处理油棕空果串纤维增强高密度聚乙烯复合材料的热力学性能

摘要油棕空果串 (OPEFB) 使用真空烘箱在 180°C 下热处理一小时，挤出并与 10%、20% 和 30% 重量分数的高密度聚乙烯复合。然后将复合材料注塑成哑铃形试样。使用热重分析 (TGA) 和差示扫描量热法 (DSC) 研究了成分和热处理对复合材料热性能的影响。还使用 Instron 万能试验机测试了拉伸和弯曲性能。TGA 显示热处理复合材料的降解峰值温度增加。DSC 显示，当热处理的空果串用作填料时，基质的结晶度 (Xc) 呈增加趋势。对于处理过的纤维复合材料，观察到拉伸模量和拉伸应变的增加。此外，处理过的纤维复合材料的拉伸强度值增加了，纤维负载量较低。
