| 目的 对无伞空投箱所用的碳纤维、玻璃纤维、芳纶纤维/环氧树脂体系纤维混杂铺层的复合材料层合板进行研究，以在低成本下提高实现效果。方法 复合材料层合板分为10层，采用层间混杂结构，通过改变混杂比、铺层角度及铺层顺序，设计148种铺层方案，利用ANSYS–APDL软件分析3种参数变量对层合板拉伸性能及抗弯性能的影响。结果 沿主要受力方向铺设纤维，碳纤维层在外侧、玻璃纤维层集中在中心，且玻璃纤维层体积分数为40%时，材料具有最高的性价比。结论 针对混杂纤维复合材料层合板，通过调整混杂比得出碳/玻璃混杂纤维复合材料性能较好，通过调整铺层角度得出纤维铺设角度越接近受力方向其性能效果越好，通过调整铺层顺序得出不同混杂比、铺层角度下的最佳性能结构。 |

| The work aims to study the composite laminates with carbon fiber, glass fiber, aramid fiber/epoxy resin system fiber hybrid layers used in the airdrop box without parachute to improve the realization effect at low cost. Composite laminates were divided into ten layers with interlaminar hybrid structure. By changing the hybrid ratio, laying angle and laying sequence, 148 laying schemes were designed. The effects of the three kinds of parameter variables on the tensile and bending properties of laminates were analyzed with ANSYS-APDL. The results showed that when the fiber was laid along the main force direction, the carbon fiber layer was on the outside, the glass fiber layer was concentrated in the center, and the volume of the glass fiber layer accounted for 40%, the material had the highest cost performance ratio. For the hybrid fiber composite laminates, it is concluded that the carbon/glass hybrid fiber composite obtained by adjusting the hybrid ratio has good performance. By adjusting the laying angle, it is found that the closer the fiber laying angle is to the force direction, the better the performance effect is. And the best performance structure under different hybrid ratio and laying angle is obtained by adjusting the laying sequence. |
