Abstract:

In order to study the complex structure of second generation of hexagonal braiding fabrics and predict its performance, an algorithm for simulating meso-structure was created for simulation using MatLab, which led to the establishment of models reflecting clearly the meso-structure. On the basis of the motion pattern of the second generation machine's horn gear, motion path of carriers was deduced which was used for coding. The trajectory of the yarn carrier were optimized through the use of B-spline, and Solidtube functions were used to carry out the simulation, leading to the visualization of the micro-structure. The algorithm in this text was designed on the basis of the most fundamental relation between horn gears and switch, thus it is universal to simulate hexagonal braiding structure, and the structure created by the algorithm to simulate also provided a better tool for unit cell division in finite element method. The braiding experiments of different hexagonal preforms were carried out. The results show that appearance of the simulated braiding structure resembles the experimental products, which verifies the accuracy of the algorithm.
