项目摘要

Braided fabrics provide an ideal preform for textile composite materials while the structure of the braided fabric is restricted by the machine braiding procedure. A wide variety of braided structure found in historical Japanese braids, however, implies a possibility for, us to obtain a more rational preform. In this study, a systematic approach to translate the structure of historical braids into machine braiding procedure was developed. The structures, bundle path diagrams and number of bundles of the hand-manipulated, historical braids were determined. Formulas giving the optimum number of bundles were derived and a method of horn-gear arrangement necessary for the rotary braiding process was developed. Finally new braiding machine was developed according to the above method. Moreover to understand the relationship between braiding structure and the mechanical properties, fiber orientation model considering shape of fiber bundle and deformation model for braided fabric were proposed. The following results were obtained;1.The bundle path and number of bundled of braided fabric was determined and formulas giving optimum number of bundles were derived.2.A method of horn-gear arrangement necessary for the rotary braiding process was developed and new braiding machine was developed.3.Internal structure of braided fabric was clarified and fiber orientation state was predicted by using CAE method.4.A series of design methodology consists of design of braiding machine, braided fabric, braided composite was developed.

编织织物为纺织品复合材料提供了理想的预成型，而编织织物的结构受机器编织过程的限制。然而，日本历史辫子中发现的各种编织结构意味着我们有可能获得更合理的预成型。在这项研究中，开发了一种系统的方法，将历史编织的结构转化为机器编织程序。确定了手工操纵，历史辫子的结构，捆绑路径图和捆绑包。得出了给出最佳束数量的公式，并开发了旋转编织过程所需的角齿状装置方法。最后，根据上述方法开发了新的编织机。此外，为了解编织结构与机械性能之间的关系，提出了考虑纤维束形状和编织织物变形模型的光纤取向模型。获得了以下结果； 1.确定了捆绑路径和捆绑的编织织物的数量，并得出了最佳的捆绑包的公式。2.开发了旋转编织过程所需的旋号钉布置方法，开发了新的编织机，并开发了新的编织机。3。编织结构的内部结构澄清，并通过CAE启用了CAE的构造方法。织物，编织的复合材料。
