Abstract
3D quadrangular rotary braiding is one vital technique of high efficiency and flexibility to manufacture preforms for composites. However, the use of this technique is limited to fabricating a few traditional braided fabric structures, which is attributed to the lack of knowledge of its process. Therefore, a model is proposed to simulate the braiding process so as to develop new processes and corresponding fabric structures. First, yarn interlacement patterns under individual propelling of the horn-gear and switch are depicted, which preliminary supplies a reference to the selection of process parameters. Then, the braiding process is digitized based on a novel mixed coordinate system, which constructs the relation between the process and carrier path. Combined with the algorithm transforming carrier path to yarn trajectories, the process-structure model is established. Afterward, the effect of horn-gear and switch movement on the yarn interlacement pattern is illustrated, which further clarifies the utilization principle of braiding process parameters. Several interesting novel braided structures including the surface-core structure are found, which shows the potential of this technique. At last, a new multi-layer interlock structure is created by modifying part of the process parameters of traditional 3D braided structure, which verifies the correctness of above model and effects.
