摘　　要：为了提升建筑工程用纤维复合材料的拉伸性能,设计了不同叠层顺序、铺层层数的碳纤维复合板,并对比了传统工艺和新型工艺下碳纤维复合板的拉伸性能和断口形貌。结果表明,碳-铝复合板的最大拉伸载荷(2.22 kN)明显高于铝-碳复合板(0.67 kN),且相较于铝-碳复合板,断裂后碳-铝复合板的位移相对更大;随着铺层层数增加,碳-铝复合板的拉剪面积逐渐增加,拉伸强度呈现先增加后减小的趋势,在铺层层数为16时取得拉伸强度最大值。传统工艺下碳纤维复合板的最大拉伸载荷为1.53 k N,而新型工艺下碳纤维复合板的拉伸载荷为2.22 kN,约为传统工艺下碳纤维复合板最大载荷的1.45倍。In order to improve the tensile performance of fiber composite materials used in construction engineering,carbon fiber composite boards with different stacking sequences and number of layers were designed,and the tensile performance and fracture morphology of carbon fiber composite boards under traditional and new processes were compared.The results showed that the maximum tensile load of carbon aluminum composite plate(2.22 kN)was sig⁃nificantly higher than that of aluminum carbon composite plate(0.67 kN),and compared to aluminum carbon com⁃posite plate,the displacement of carbon aluminum composite plate after fracture was relatively greater.As the num⁃ber of layers increased,the tensile and shear area of carbon aluminum composite plates gradually increased,and the tensile strength showed a trend of first increasing and then decreasing.The maximum tensile strength was achieved when the number of layers was 16.The maximum tensile load of carbon fiber composite board under traditional tech⁃nology was 1.53 kN,while the tensile load of carbon fiber composite board under new technology was 2.22 kN,which was about 1.45 times the maximum load of carbon fiber composite board under traditional technology.
