摘　　要：研究了Pin植入角、Pin直径和Pin材料对X-cor夹层结构平拉强度及平拉模量的影响。平拉性能试样采用Rohacell 31泡沫作为芯材,Pin采用不同直径的T300/FW-63和SC-240/FW-63拉挤细杆。结果表明,X-cor夹层结构平拉强度增强效率随着植入角度的增加先增大、后减小,平拉模量的增强效率则随植入角的增加而减小;随Pin直径减小,平拉强度增强效率增加,平拉模量增强效率降低;不同Pin材料对X-cor夹层结构平拉强度增强效率相同,高模量的Pin对X-cor夹层结构平拉模量的增强效率更高。To experimentally study the influence of pin＇s angle and diameter and pin materials on the strength and modulus of X-cor sandwich structures,the specimens of flatwise tensile test were made of the Rohacell 31 foam core and the pins with different kinds of diameter consisting of T300/FW-63 carbon/epoxy and SC-240/FW-63 glass/epoxy with pultrusion process.The results show that the efficiency of pin reinforcing flatwise tensile strength of X-cor sandwich structures increased first and then decreased as pin＇s angle increased and increased as pin＇s diameter decreased,the efficiency of pin reinforcing flatwise tensile modulus of X-cor sandwich structures decreased as pin＇s angle increased and decreased as pin＇s diameter decreased,the efficiency of pin reinforcing flatwise tensile strength of X-cor sandwich structures is keep constant with different pins materials,but the efficiency of pin reinforcing flatwise tensile modulus of X-cor sandwich structures is higher with higher modulus pins.
