摘　　要：现有线弹性理论难以计算铝合金与碳纤维(Al/CFRP)复合材料层合板的拉伸及冲击强度,故本文提出一种适用于Al/CFRP层合板的强度计算公式,并利用实验方法获取系数。选用1060H18铝合金和T300碳纤维材料,采用自成形黏接方法制备Al/CFRP复合材料层合板试件,进行单轴拉伸实验和低速落锤冲击实验,验证公式的合理性。结果表明,用该公式计算得到的Al/CFRP层合板拉伸强度和抗冲击强度的理论值与实测值误差均小于3%,与原公式计算值相比,准确率分别提升63.23%和65.58%,可以预测Al/CFRP层合板的拉伸强度及冲击强度,为Al/CFRP层合板的推广和应用提供参考。It is difficult to calculate the tensile and impact strength of aluminum alloy and carbon fiber(Al/CFRP)composite laminates in the existing linear elastic theory,so a strength calculation formula suitable for Al/CFRP laminates is proposed,and the coefficients are obtained by experimental methods.1060H18 aluminum alloy and T300 carbon fiber materials were selected to prepare Al/CFRP composite laminate specimens by self-forming bonding method,and uniaxial tensile tests and low-speed drop weight impact experiments were carried out to verify the rationality of the formula.The results show that the theoretical and measured errors of the tensile strength and impact strength of Al/CFRP laminates calculated by this formula are less than 3%,and the accuracy is increased by 63.23% and 65.58% respectively compared with the calculated values of the original formula,which can predict the tensile strength and impact strength of Al/CFRP laminates,and provide a reference for the promotion and application of Al/CFRP laminates.
