面向一体化设计的船用碳玻混杂复合材料帽型加筋板结构多尺度分析
Multi-scale analysis of marine carbon/glass hybrid composite top-hat stiffened panel structure for integrated design
摘要
Abstract
[Objective]As composite material design and structural design are separated in the"dual track"state,this paper proposes an integrated design method for composite materials in order to improve the ultimate strength of marine composite structures.[Methods]Based on the multi-scale method,the correlation between the meso-scale material and macro-scale structure is established,and the influence of the meso-scale parameters on the ultimate strength of macro-scale stiffened panels is explored,as well as the differences in mechanical properties between intra-layer and inter-layer hybrid carbon/glass fiber composite material.Through comparison,the superior structural form is obtained.[Results]The proposed micro-meso-macro mechanical analysis method can improve the ultimate strength of macro-scale stiffened panels by enhancing the meso-scale parameters of composite materials.By adjusting the spacing and cross-sectional area of TC33 yarn,cross-sectional area of WR yarn,and mixing mode,the designed composite top-hat stiffened structure has better ultimate strength.[Conclusions]The results of this study show that the integrated design of ma-terial and structure can be realized through multi-scheme comparison and optimization while satisfying the re-quirements of the rules,providing theoretical guidance and technical support for the novel design of naval ships.关键词
