摘　　要：采用快速模压成型法制备了建筑隔震碳纤维复合材料,研究了模压压力、加压温度和固化温度对碳纤维复合材料拉伸性能和摩擦性能的影响。结果表明,当模压压力从6 MPa上升至14 MPa时,碳纤维复合材料的拉伸强度和标准化拉伸强度都呈现先增加后减小,摩擦系数表现为先减小后增大;当加压温度从100℃上升至130℃时,碳纤维复合材料的拉伸强度和标准化拉伸强度都先增大后逐渐减小,摩擦系数表现为先减小后增大;当固化温度从130℃上升至160℃时,碳纤维复合材料的拉伸强度和标准化拉伸强度都先增大后逐渐减小,摩擦系数表现为先减小后增大的趋势。适宜的建筑隔震碳纤维复合材料制备工艺为:模压压力10 MPa、加压温度110℃、固化温度140℃。Seismic isolation carbon fiber compositeswere prepared by rapid molding method.The effects of molding pressure,compression temperature and curing temperature on the tensile and friction properties of carbon fiber com⁃posites were studied.The results showed that when the molding pressure increased from 6 Mpa to 14 MPa,the ten⁃sile strength and standardized tensile strength of carbon fiber composites increased first and then decreased,and the friction coefficient decreased first and then increased.When the pressure temperature risedfrom 100℃to 130℃,the tensile strength and standardized tensile strength of carbon fiber composites first increasedand then gradually decreased,and the friction coefficient first decreased and then increased.When the curing temperature rised from 130℃to 160℃,the tensile strength and standardized tensile strength of carbon fiber composites first in⁃creased and then gradually decreased,and the friction coefficient first decreased and then increased.The suitable preparation process of building seismic isolation carbon fiber composites is:molding pressure 10 MPa,pressuriza⁃tion temperature 110℃,curing temperature 140℃.
