| 摘 要： | X-cor结构是一种采用拉挤复合材料细杆（Pin）以三维网架结构形式增强泡沫的新型夹层结构材料，该夹层结构与传统泡沫夹层结构和蜂窝夹层结构相比，具有很高的比强度和比刚度。为了研究Pin植入角、Pin直径对X-cor夹层结构压缩强度和压缩模量的影响，压缩性能试样采用Rohacell 31泡沫作为芯材，Pin采用0.5 mm和0.7 mm两种不同直径的T300/FW 63碳/环氧拉挤细杆，并将实验结果与不含Pin增强的泡沫夹层结构进行了对比。研究结果表明，Pin的存在极大提高了X-cor夹层结构的压缩强度、压缩模量，同时密度仅小幅度提升；Pin对X-cor夹层结构压缩性能的增强效率随Pin植入角的减小而提高，采用小直径的Pin更利于提高X-cor夹层结构压缩性能。
