摘要
本文采用浇注方法制备了苍耳茎/环氧树脂复合材料,详细研究了苍耳茎含量对复合材料力学性能和吸水率的影响。实验结果证实:当苍耳茎含量达到10%时,环氧树脂复合材料具有最优的力学性能,此时复合材料的弯曲强度为54.8 MPa,冲击强度也达到4.615 kJ/m2,拉伸强度和拉伸模量分别达到32.4 MPa和6279.5 MPa。复合材料吸水率最低达到0.929%。这主要是因为苍耳茎粉末与环氧树脂呈现良好的界面性能所致。
Xanthium sibiricum stem/epoxy resin composite material was pro-duced by using a casting manufacture. The effects of xanthium sibiricum stem on the mechanical properties and water absorption of the composite material were investigated in detail. The experi-mental results confirmed that when the stem content of Xanthium sibiricum reaches 10%, the epoxy resin composite material has the optimal mechanical properties. At this time, the flexural strength of the composite material is 54.8 MPa, the impact strength also reaches 4.615 kJ/m2, in addition, the tensile strength and modulus reach 32.4 MPa and 6279.5 MPa, respectively. The water absorption rate of composite materials reaches the minimum value of 0.929%. This is mainly due to the good interfacial performance between the powders of xanthium sibiricum stem and epoxy resin.
