摘　　要：采用天然植物纤维材料如麦秆、花生杆、花生壳、玉米秆与剑麻、玉米芯、涤纶布共混，由模压成型工艺制备了混杂植物纤维增强树脂复合材料，对其密度、吸水性及力学性能进行了测试，并由SEM观察了其微观形貌。结果表明，复合材料的最佳制备工艺为：填料的麦秆，花生杆与花生壳质量比60：20：20，环氧胶粘剂添加质量分数8％，热压温度120℃，热压压力10MPa，制备的混杂植物纤维增强复合材料密度低于1，平均拉伸强度达到14MPa，努氏硬度〉400kg／mm2，基本符合GB／T30672-2014要求。Using natural plant fiber materials such as wheat straws, peanut stalks, peanut shells, corn stalks and blending them with sisal, corn cobs and polyester fabrics, a hybrid plant fiber reinforced composites was prepared by compression molding. The density water absorption and mechanical properties of the composites were tested, and the morphology was observed by SEM. The results showed that the best preparation process for composite materials was as follows：filler （wheat straws ,peanut stalks and peanut shells ） mass ratio 60 ： 20 ： 20 ; epoxy adhesive amount 8wt%, hot-pressing temperature 120 ℃ and hot-pressing pressure 10 MPa.The prepared hybrid plant fiber reinforced composites had a density lower than 1 ,an average tensile strength of 14 MPa, and a Knoop hardness higher than 400 ,basically meeting the requirement of GB/T 30672-2014.
