摘要
混杂是提高复合材料力学性能的一种有效途径。本文通过对三维编织预制件纱线运动路径进行研究,提出了层内混杂和层间混杂三维编织复合材料的设计与制备方法。根据上述研究,制备了层内混杂三维编织复合材料,采用树脂共固化法制备了两层和四层层间混杂三维编织复合材料,并对三种混杂三维编织复合材料进行了低速冲击性能测试。结果表明,混杂方式是影响三维编织复合材料冲击性能的重要因素,在面内冲击和轴向冲击下,冲击性能由强至弱排序为层间混杂(4层)三维编织复合材料>层间混杂(2层)三维编织复合材料>层内混杂三维编织复合材料。本文的研究结果可为三维编织复合材料的性能优化提供一种有效可行的方式。
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.
