厚度增强复合材料研究现状及进展

Development of Composite Laminates with Through-thickness-reinforcements

简单介绍了厚度方向增强复合材料的优点及缺点。重点综述了Z-pinned增强复合材料由于pin的插入造成的对复合材料分层破坏的抑制,微观损伤以及由于损伤带来的面内力学性能的下降;同时,对国内外近年来发表的Z-pinned复合材料层合板面内力学性能的实验结果和理论预测模型进行了分析比较。最后,对厚度增强复合材料面内力学性能的研究提出了几点建议。

The advantages and disadvantages of composite laminates with through-thickness-reinforcements are briefly introduced. Inhibition effects of delamination , micro damage and declination of mechanics properties caused by micro-damage are reviewed emphatically. And the paper analysis and compared experiment results and theoretical models on in-plane mechanical properties of Z-pinned reinforced composite laminate in paper dehvered recently years. Finally, some advices are given for research on in- plane mechanics properties of composite reinforced in thickness.
