摘要
[目的]复合材料设计与结构设计一直处于分离的"双轨"状态,旨在提升船用复合材料结构的极限强度,提出复合材料与结构一体化设计方法.[方法]基于多尺度方法,建立细观材料与宏观结构的尺度关联,探究细观参数对宏观加筋板极限强度的影响以及碳玻层内混杂与层间混杂的力学性能差异,通过对比分析获得更优结构形式.[结果]采用建立的微-细-宏观力学模型,改善了复合材料细观参数,提高了宏观加筋板极限强度.通过调整TC33 纱线间距和纱线截面积、WR纱线截面积、混杂方式,使得设计的复合材料帽型加筋结构具有更优的极限强度.[结论]通过多方案对比寻优,在满足规范要求的前提下可实现材料与结构一体化设计,为新一代舰船设计提供理论指导和技术支撑.
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.
