Integrated design for manufacturing of braided preforms for advanced composites Part II : 3D Braiding

摘要

This paper presents the integrated design of manufacturing of braided preforms by two types of novel 3D braiding technology: 3D Cartesian braiding and novel hexagonal braiding. The principles for design are first introduced and the ensuing software package development is subsequently discussed. The relationships between fiber volume fraction and braiding angle which are key parameters for fiber reinforcement composites were analyzed and compared. Meanwhile, several samples are carried out to verify the software. The result shows it is consistent between theoretical and experimental results. Combined with the Part I: 2D braiding section, many complex shape performs can be made, which will be usefully for design of advanced composites.
