摘　　要：复合材料的结构一体化技术包括结构整体化和结构 功能一体化两个方面。复合材料吸能结构属于典型的结构 功能一体化结构。以复合材料管形件为基础,发现提高管形件轴向性能如增加编织结构的轴向纤维纱数,或调整预浸料复合材料铺层尽可能地平行于轴向,或提高复合材料层间韧性(即高CAI值)等,都有利于提高吸能效果。在整体化制造方面,研制和验证了织物复合材料正弦波梁的液态成型制造技术。Both integrated composite structure and function- integrated composite structure are target of advanced manufacturing technology in aircraft industry. Energy absorption structure is typically function-integrated structure. For composite tubes, it was found that the energy absorption behavior was increased by increasing the axial tows for braided structure, or by laying-up the prepregs orientated in the axial direction, or by increasing the interlaminar toughness. For integrated aircraft structure, sine wave beams were fabricated and demonstrated by using the textile fabrics and liquid molding.
