摘　　要：为了研究蜂窝夹层复合材料的力学性能,本文使用三种牌号单向预浸布、不同面密度胶膜以及一种Nomex蜂窝芯材通过热压一体成型工艺制备蜂窝夹层复合材料。研究了蜂窝夹层板的滚筒剥离、长梁弯曲、板剪切(三点弯曲)以及嵌件剪切性能的影响因素。研究结果表明使用相同Nomex蜂窝芯材时:胶膜面密度对蜂窝夹层板的滚筒剥离性能影响显著;蜂窝夹层板的长梁弯曲性能和450 N载荷下的挠度主要受预浸布影响;预浸布和胶膜对蜂窝夹层板的板剪切性能影响较小;蜂窝夹层板的嵌件剪切性能和胶膜面密度无明显关系,受预浸布影响较大。Honeycomb sandwich composites were prepared by using three brands of unidirectional prepreg,one type of multi-surface density adhesive film and a type of Nomex honeycomb core,through a hot-pressing process.The paper studies the effect of the surface density of adhesive film on climb drum peeling of honeycomb sandwich panel,and the factors which affect the long beam bending,panel shearing(three-point bending)and insert shearing.When using the same Nomex honeycomb core material,the results are as follows.The surface density of the adhesive film has obvious influence on the climb drum peeling performance of the honeycomb sandwich panel.The long beam bending load of the honeycomb sandwich panel is mainly affected by the performance of the prepreg.The deflection under 450 N load is controlled by the modulus of prepreg after curing.The effect of prepreg and adhesive film on the performance of panel shearing of sandwich panel is small.The performance of insert shearing has nothing to do with the surface density of the adhesive film.
