ABSTRACT The aim of the paper was to determine the mechanical, thermal, and morphological properties of heat-treated wood-polypropylene polymer composites (WPCs) and to select the composites having the optimum properties with the PROMETHEE method. In this study, polypropylene (PP) as a matrix, wood thermally treated at 180°C and 220°C as reinforcement filler were examined for preparing composites. The PP composites were compounded using a twin-screw extruder and test specimens were prepared by compression moulding. According to the test results, the thermal and mechanical properties of the WPCs generally increased with the addition of heat-treated wood fillers. The SEM images showed that the wood fillers dispersed better in the PP matrix as the particle size decreased from 40 mesh to 100 mesh. The WPCs having the optimum mechanical and thermal properties were determined for 40 mesh heat-treated wood at 220°C and 20 wt-% loadings with PROMETHEE method.

热处理木-聚丙烯复合材料的力学、热学和形态学性能以及复合材料与 PROMETHEE 方法的比较

摘要 本文的目的是确定热处理木材-聚丙烯聚合物复合材料 (WPC) 的机械、热和形态特性,并使用 PROMETHEE 方法选择具有最佳性能的复合材料。在这项研究中,聚丙烯 (PP) 作为基体,木材在 180°C 和 220°C 下作为增强填料进行热处理,以制备复合材料。PP 复合材料使用双螺杆挤出机进行复合,并通过压缩成型制备试样。根据测试结果,WPCs 的热性能和机械性能普遍随着热处理木材填料的加入而增加。SEM 图像表明,随着粒径从 40 目减小到 100 目,木材填料在 PP 基体中的分散性更好。
