The invention relates to the field of composite materials, in particular to a tear-resistant bearing structure of an aerostat capsule material and application of the tear-resistant bearing structure. The structure is formed by laminating a fiber fabric and a thermoplastic polyurethane film, and warp weave points and weft weave points are uniformly distributed on the surface of the fiber fabric to form inclined opposite stripes. The fiber fabric is composed of a plurality of weave basic circulation units, and each weave basic circulation unit is composed of twill weave points and complementary weave points symmetrically distributed along the Y axis. According to the tear-resistant force bearing structure of the capsule material, the preparation of the high-tear capsule material is realized by adopting a simple and convenient method, and compared with the existing capsule material prepared by adopting a plain force bearing structure and a square force bearing structure, and the force bearing structure has the advantages that the defects of no tight warp, non-uniform tension and the like on a cloth cover, high flatness of the cloth cover and the like.
本发明涉及复合材料领域,具体涉及一种浮空器囊体材料的抗撕裂承力结构及应用。由纤维织物和热塑性聚氨酯薄膜层压而成,所述纤维织物表面均匀分布有经组织点和纬组织点,组成斜条相向条纹。所述纤维织物是由多个组织基本循环单元构成,所述的组织基本循环单元是由斜纹组织点及其沿Y轴对称分布的互补组织点组成。本发明提供的一种囊体材料抗撕裂承力结构,采用一种较为简便方法实现高撕裂囊体材料制备,较现用平纹承力结构、方格承力结构制备的囊体材料,承力结构具有布面无紧经、张力不匀等缺陷及布面平整性好等优点。
