双轴编织套管通常用于通过气囊充气成型生产中空复杂形状的复合材料零件。为了进行可行性分析、零件设计和预测所得纤维增强部件的机械性能，必须了解处于悬垂状态的编织物的各种几何和重量相关参数，例如纤维取向、纤维体积分数和面积重量。在目前的工作中，建立了一个全面的分析模型，描述织物形成、预成型件结构和重量以及双轴编织套管在悬垂过程中相关纺织参数的变化。主要建模方法基于文献中的零星研究，并进行了大幅扩展，以编制广泛的关系集合，以供在套管预成型过程中使用。此外，还对管状二维编织结构的几何建模领域的最新技术进行了重要概述，并对所确定的程序与所需应用进行了比较。
Biaxial braided sleevings are commonly used for producing hollow complex-shaped composite parts through bladder inflation moulding. To enable feasibility analyses, part design and the prediction of mechanical properties of the resulting fibre-reinforced component, various geometrical and weight-related parameters of the braided fabric in its draped state must be known, such as fibre orientation, fibre volume fraction and areal weight. In the present work, a comprehensive analytical model describing fabric formation, preform architecture and weight as well as the change of relevant textile parameters of a biaxial braided sleeving during draping is established. The principal modelling approach is based on sporadic investigations found in literature and was substantially expanded to compile an extensive collection of relationships for the utilisation in a sleeving-on preforming process. Furthermore, a critical overview about the state of the art in the area of geometrical modelling of tubular 2D braided structures and a comparison of the identified procedures in regard to the desired application is given.
