摘要
由于夹芯结构具有比强度高、比模量大等众多优点,目前被广泛应用在航空航天等领域。从面板、芯子和面芯界面加强技术等三个方面对夹芯结构的设计和制备现状进行了介绍。重点对蜂窝夹芯结构、泡沫夹芯结构、点阵夹芯结构、格栅夹芯结构和整体夹芯结构等的设计和制备工艺以及为了提高面芯界面结合强度而不断被提出的包括Z-Pin,Stitch和Embedding等在内的面芯界面增强工艺进行了较为系统的介绍。
Sandwich structures have been widely applied in astronautics and aeronautics fields. In comparison with traditional materials, sandwich structures have many advantages, namely high stiffness-to-weight ratio, high strength-to- weight ratio, and so on. The advances in design and manufacturing of sandwich structures, including facesheets, cores and interracial reinforced technique, are presented. The design and fabrication process of several kinds of sandwich struc- tures including honeycomb sandwich, foam sandwich, truss sandwich, grid sandwich and 3D integrated sandwich, and interracial reinforced techniques such as Z-Pin, Stitch and Embedding, have been introduced in detail.
