采用国产BHM3和进口M40、M40J高模量碳纤维分别与环氧4211和改性氰酸酯 BS-4树脂制备复合材料层合板，再与铝蜂窝芯组合制成蜂窝夹层结构件。对比检测两类结构件的平面拉伸和弯曲性能，以及其内置金属接头的承载能力，并通过碳纤维表观形貌和碳纤维增强树脂基复合材料的界面性能对测试结果进行分析验证。结果表明，与同种树脂基体复合，国产BHM3碳纤维制备蜂窝夹层结构件的性能已显著优于进口M40碳纤维，部分性能已接近或优于进口M40J碳纤维；相比较于环氧4211树脂基体，改性氰酸酯BS-4树脂更有利于提高国产BHM3碳纤维复合材料的力学性能。%This paper focused on the performance evaluation of honeycomb sandwich structure samples, which were manufactured by carbon fiber reinforced composite laminates and aluminum honeycomb core. The different laminates were prepared by the high modulus carbon fiber of BHM3, M40 and M40J and the resin of 4211 (epoxy resin) and BS-4 (cyanate ester resin). The plane stretching and bending properties of the honeycomb sandwich structural parts using the different matrix resins as well as the maximal failed load of the embedded metal tooling into the structure were compared. Furthermore, the carbon fiber morphology and interfacial properties of the studied composite materials were investigated to explain the research results. The results show that the properties of the honeycomb structural parts using BHM3 carbon fiber are obviously prior of that using M40 carbon fiber and are basically close to that using M40J carbon fiber when the matrix is identical. Additionally, the properties of the honeycomb structural parts using BS-4 resin are higher than that using 4211 resin when the reinforced fiber is same.
