In order to improve the properties of bamboo‐plastic composites (BPCs), bamboo flour/high‐density polyethylene (HDPE) composites were reinforced with ultrahigh molecular weight polyethylene (UHMWPE). The effects of UHMWPE on properties of composites were studied. The crystallinity of composites decreased slightly. Compared with non‐UHMWPE added bamboo powder/HDPE composite, the composite with 6 wt % UHMWPE, showed decrease in water absorption to 0.41%, whereas its tensile strength and flexural strength increased to 34.51 and 25.88 MPa, respectively, a corresponding increase of 34.59 and 12.87%. The temperatures corresponding to initial degradation temperature (T initial) and maximum degradation temperature (T max) of the composite increased from 282.7 and 467.4 °C to 288.5 and 474.7 °C respectively. Scanning electron microscopic images showed that UHMWPE was well dispersed and fully extended as long fibers in the composite, forming a “three‐dimensional physically cross‐linked network structure,” which contributed to the improved properties of the composites. © 2020 Wiley Periodicals, Inc.

超高分子量聚乙烯增强竹粉/高密度聚乙烯复合材料的性能

为了改善竹塑复合材料(BPC)的性能,用超高分子量聚乙烯(UHMWPE)增强了竹粉/高密度聚乙烯(HDPE)复合材料。研究了超高分子量聚乙烯对复合材料性能的影响。复合材料的结晶度略有下降。与未添加UHMWPE的竹粉/ HDPE复合材料相比,UHMWPE为6 wt%的复合材料的吸水率降低至0.41%,而其抗张强度和抗弯强度分别增加至34.51和25.88 MPa,分别增加了34.59和12.87%。对应于初始降解温度(T initial)和最大降解温度(T max)的温度复合材料的)分别从282.7和467.4°C升高到288.5和474.7°C。扫描电子显微镜图像显示,UHMWPE很好地分散并作为长纤维在复合材料中充分延伸,形成了“三维物理交联的网络结构”,这有助于改善复合材料的性能。©2020 Wiley Periodicals,Inc.
