Abstract

Abstract: Hybrid is an effective way to improve the mechanical properties of composite materials. In this paper, based on the study of yarn motion path of three-dimensional (3D) braided prefabricated parts, the design and preparation methods of intralaminar hybrid and interlaminar hybrid 3D braided composites were presented. According to the above research, the intralaminar hybrid 3D braided composites were prepared, and the interlaminar hybrid (2 layers) and interlaminar hybrid (4 layers) 3D braided composites were prepared by resin co-curing method. The low-speed impact properties of the three hybrid 3D braided composites were tested. The results showed that hybrid mode was an important factor affecting the impact properties of 3D braided composites. Under in-plane impact and axial impact, the impact properties were as follows: interlaminar hybrid (4 layers) 3D braided composites > interlaminar hybrid (2 layers) 3D braided composites > intralaminar hybrid 3D braided composites. The research results in this paper can provide an effective and feasible way to optimize the properties of 3D braided composites.
