| 摘 要： | 进行了碳纤维增强复合材料蜂窝夹芯板低速冲击试验及冲击后面内单向压缩试验,并采用解析解方法对含低速冲击损伤的复合材料蜂窝夹芯板在面内单向压载作用下的损伤扩展过程进行了预测与分析,分析结果与试验结果吻合较好.研究进一步扩展了解析解模型,使之能够预测和分析在面内双向拉压载荷作用下含低速冲击损伤的复合材料蜂窝夹芯结构的损伤扩展特性.分析结果表明,施加面内横向拉伸载荷会延迟复合材料蜂窝夹芯结构在面内纵向压载作用下低速冲击损伤扩展过程,从而提升结构在纵向的残余压缩强度.

| Abstract: | Low-velocity impact tests and sandwich compression after impact tests are performed on carbon fiber reinforced composite honeycomb sandwich panels.The damage propagation behavior of low-velocity impacted sandwich panels under in-plane uniaxial compression is analyzed by using an analytical model.Analytical results are in good agreement with experimental data.The analytical model is modified with expanded capabilities to predict the damage propagation behavior of low-velocity impacted sandwich panels on in-p... |
