为进一步改善基于农林剩余物的木基复合粉末的温压成形综合性能，开发新型复合材料，以芦苇秆粉末（Reed）为基材、紫铜粉末（Cu）为强韧化因子、聚乙烯（PE）为紫铜粉末分散助剂，运用响应面试验法、三维立体数码显微镜、扫描电镜和电子万能材料实验机等方法和手段研究PE及Cu对温压成形Reed/Cu/PE复合材料性能的影响，对试件材料的性能与结构进行表征。结果表明：Reed/Cu/PE复合材料的最优温压成形工艺条件为，PE和Cu质量分数分别为10％和17％；制备的Reed/Cu/PE复合材料的静曲强度、表观硬度（HV）、吸水率和吸水厚度膨胀率分别达到了49．26、9．267 MPa、3．32％和4．35％。

We developed new composite materials and improved the overall performance of composites based on agriculture and forestry residues by warm compaction with reed powder as substrate, copper powder as strengthening factor and polyethy-lene ( PE) as dispersing additives.We used the response surface method, three-dimensional digital microscope, scanning electron microscopy, electronic universal material testing machine and other means to study the effect of PE and Cu content on properties of Reed/Cu/PE composite by warm compaction, and then obtained the specimen’ s properties and structural characteristics.The best processing conditions are with PE content of 10%and Cu content of 17%.The static bending strength, apparent hardness, water absorption, water absorption and thickness swelling of the composite were 49.26 MPa, 92.67 HV, 3.32%and 4.35%, respectively.
