Abstract

Abstract: The torsion behavior of a three-dimensional (3D), 4-directional braided composite shaft was investigated using digital image correlation (DIC) and acoustic emission (AE). The 3D, 4-directional braided composite shafts with various braiding angles were prepared using vacuum assisted resin transfer molding (VARTM). The torsion experiments were performed on a static torsion machine. The 3D DIC and AE were used to capture the surface deformations and the acoustic emission characteristics of the shaft. The full-field 3D deformations and the AE characteristics were obtained, and the failure mode and mechanism of the 3D, 4-directional braided composite shaft were analyzed. The results will have an important role in the design and application of 3D, 4-directional braided composite shafts in engineering. Highlights: The 3D 4-directional braided composite shafts were prepared using VARTM. The 3D DIC was used to capture the surface deformations of the shafts. The AE was used to capture the emission characteristic of the shafts. The failure mode of the 3D 4-directional braided composite shaft was analyzed. The failure mechanism of the 3D 4-directional braided composite shaft was analyzed.
