摘要

本工作探讨了熔融沉积建模(FDM)生产红麻纤维/热塑性聚氨酯(TPU)复合材料的可行性。利用内混机将不同重量百分比(0、5、10 wt %)的红麻纤维与TPU混合，然后挤压制成FDM原料长丝。红麻纤维的加入有利于印刷样品的尺寸稳定性，这对其在FDM中的实施具有重要意义。添加10wt%红麻纤维的TPU硬度和杨氏模量分别提高15%和49%。然而，随着红麻纤维负荷的增加，打印样品的抗拉强度、断裂伸长率和密度下降。这可能是由于材料内部的空隙和孔隙增加以及TPU基质与红麻纤维之间的润湿性差，这一点可以通过SEM观察得到解释。

Fused deposition modelling of flexible kenaf fiber/thermoplastic polyurethane composites

This work explores the feasibility of fused deposition modelling (FDM) to produce kenaf fiber/thermoplastic polyurethane (TPU) composites. Internal mixer was used for mixing different weight percentage (0, 5 and 10 wt %) of kenaf fiber with TPU before being extruded to produce filament for FDM feed stock. Addition of kenaf fiber was found to give benefits on dimensional stability of the printed samples which is importance for its implementation in FDM. TPU filled with 10wt% of kenaf fibre showed improvements in hardness and Young modulus of 15% and 49%. However, the tensile strength, elongation at break and density of the printed samples decreased with increasing kenaf fiber loading. This could be explained due to increase of voids and porosity within the material and poor wettability between TPU matrix and kenaf fiber which is evidenced by SEM observation.
