A novel wood flour (WF)-filled composite based on the microfibrillar high-density polyethylene (HDPE) and Nylon-6 co-blend, in which both in situ formed Nylon-6 microfibrils and WF acted as reinforcing elements, was successfully developed using a two-step extrusion method. At the 30wt.% WF loading level, WF-filled composite based on the microfibrillized HDPE/Nylon-6 blend exhibited higher strengths and moduli than the corresponding HDPE-based composite. The incorporation of WF reduced short-term creep response of HDPE matrix and the presence of Nylon-6 microfibrils further contributed to the creep reduction.
采用两步挤出法成功制备了一种新型木粉（WF）填充复合材料，该复合材料基于微纤化高密度聚乙烯（HDPE）和尼龙 6 共混物，其中原位形成的尼龙 6 微纤维和 WF 均作为增强相。在 30wt.% WF 填充量下，基于微纤化 HDPE/尼龙 6 共混物的 WF 填充复合材料表现出比相应的 HDPE 基复合材料更高的强度和模量。WF 的加入降低了 HDPE 基体的短期蠕变响应，而尼龙 6 微纤维的存在则进一步有助于降低蠕变。
