摘要

将复合材料三维编织结构优越特性与T 型接头整体化需求相结合，采用树脂传递模塑RTM 液体成型工艺，设计制造了三维六向编织复合材料T 型接头，针对不同的编织角（20°、30°、40°）及不同的纱线束（6k、9k、12k）下的拉脱性能进行试验研究。试验结果表明，在拉脱载荷作用下，编织角对三维六向编织T 型接头的拉脱性能影响很大，编织角从20° 变为40° 时，拉脱载荷提高了53% ；而纱线束对三维六向编织T 型接头的拉脱性能基本没有影响。纱线从6k 变为12k 时，仅增加了约8% ；拉脱破坏模式均为T 型接头的侧板与底板发生分离。研究成果对整体化复合材料结构设计及研制具有重要的试验指导作用。

Abstract

Using good inter-laminar property of three-dimensional braided composite to meet the requirement of the integral T-joints structure

a T-joints structure has been designed and manufactured with using resin transfer liquid composite molding and 3D six-directional braided composites. The pull-off damage property of the T-joints structure has been studied by tests for different braiding angles (20°

30°

40°) and yarns (6k

12k). It has been shown by the tests that the damage type of T-joints structure with 3D six-directional braided composites is the web pulling away from the flange; The T-joints structure pull-off strength increased by 53% when braiding angle changing from 20° to 40° for the same braiding yarns and by 8% when braiding yarns changing from 6k to 12k for the same braiding angle. The research results can be an important experimental guidance for the design and development of integrated composite structure.
