摘　　要：采用热固化方法制备了边坡锚固用碳纤维增强复合材料。研究了电加热固化、传统微波间接加热固化和优化后微波间接加热固化复合材料的力学及热学性能。结果表明,在电加热固化和微波间接加热固化过程的升温过程中没有出现放热峰,说明碳纤维增强复合材料在电加热固化作用下已经发生完全固化。相较于电加热固化工艺,微波间接加热固化在碳纤维增强复合材料完全固化前提下所消耗的能量仅为前者的24.97%,所需要的时间为前者的60%。微波间接加热固化碳纤维增强复合材料的拉伸性能、压缩性能、弯曲性能和层间剪切性能都高于电加热固化试样,层间剪切性能平均值相较于电加热固化提高了49.71%。Carbon fiber reinforced composites for slope anchorage were prepared by thermal curing method,and the thermal and mechanical properties ofthe composites were studied,including electric heating curing,traditional mi-crowave indirect heating curing and optimized microwave indirect heating curing.The resuls showed that there was no exothermic peak in the heating process ofthe carbon fiber reinforced composite during the electric heating cur-ing and the microwave indirect heating curing,indicating that the carbon fiber reinforced composite has been com pletely cured under the electric heating curing.Compared with the electric heating curing process,the energy con-sumed by microwave indirect heating curing was only 24.97%of the former and the time required was 60%of the former when the carbon fiber reinforced compositewas fully cured.The tensile properties,compressive properties bending properties and interlaminar shear properties of carbon fber reinforced composites cured by microwave indi-rect heatingwere higher than those cured by electric heating.The interlaminar shear properties of carbon fiber rein-forced composites cured by microwave indirect heating were lower than those cured by electric heating,while the av-erage interlaminar shear properies of carbon fiber reinforced composites cured by microwave indirect heating were 49.71% higher than those curedy electric heating.
