摘要: 结构轻量化是航空航天、车辆、船舶等领域发展的永恒主题,复合材料泡沫夹芯板是轻量化结构中的重要组成部分,一般由强度高、模量大的复合材料作为上下面板,由轻质多孔泡沫作为中间芯材。但是泡沫夹芯结构面芯脱胶失效成为制约其工程应用的主要原因。本文将对面芯增强泡沫夹芯结构复合材料的设计、制备和力学性能表征方面的最新研究成果进行总结,重点介绍缝合、簇绒和Z-pin等泡沫夹芯结构面芯增强手段以及对应的设计和制备工艺,重点从力学性能试验表征和面芯增强前后的性能对比等角度评述了面芯增强后的性能改进效果。

Abstract: Lightweight structure is an eternal theme in the development of aerospace, vehicles, ships and other fields. Composite foam sandwich panels are an important structural form in lightweight structures. Generally, high-strength, high-modulus composites panels were used as the face sheets and lightweight porous foam were used as the sandwich cores in the middle. However, the failure of debonding between the face sheets and foam core of the sandwich structure has become the essence of its engineering application. This paper summarizes the latest researches about composite foam sandwich structure with a reinforcement between face sheets and core in terms of design, fabrication and mechanical properties, focusing on the reinforcement methods of stitching, tufting and Z-pin about design and preparation process. The improvements of mechanical performance after the reinforcement between the face sheets and core is characterized from comparisons of the experimental results between the foam sandwich structures with and without reinforcement.

Key words: foam sandwich structures, composites, stitching, tufting, Z-pin
