摘要
具有空间点阵的先进复合材料格栅结构(AGS)是一种新型高效的结构形式,在航空、航天结构中具有良好的应用前景。介绍了AGS优良的各项性能以及在美、俄等国航空、航天工程中的应用现状,着重描述了混合工艺法、模具膨胀工艺和拉挤-互锁格栅结构几种现行工艺方法,并对当前国内外针对格栅结构的力学性能和结构健康监测的研究进行了概述。最后提出了AGS进一步研究的工作展望。
Advanced composite grid structure (AGS) is one of the most efficient lattice structures with many potential advantages, which own good application foreground in aeronautical and space engineering. First, the overview of the excellent performance and applications to AGS in USA and Russian are presented. Then, the discussion focuses on three kinds of manufacture toolings: hybrid tooling,expansion block tooling and interlocked grid structures. Researches on mechanical properties, design and structural health monitoring are summarized. Finally,the present research state is generalized and the trends in future are described.
