Abstract

High-performance thermoplastic composites were developed using Multi-Criteria Decision-Making (MCDM)-based smart material selection to identify optimal thermoplastics for ballistic applications. To enhance matrix impregnation, a novel commingled 3D weaving technique was devised, enabling simultaneous mixing of reinforcement and thermoplastic materials during preform fabrication. This approach eliminates the need for intimate mixing at spinning level, reducing risk of damaging reinforcement fibers during the melting of thermoplastics in composites. Nylon-6 and Polypropylene were selected through this smart selection process and combined with Kevlar high-performance fibers for fabrication. The Kevlar/Polypropylene preform demonstrated superior air permeability, ensuring uniform resin flow during composite manufacturing due to its open structure. In contrast, the Kevlar/Nylon preform exhibited better slow penetration resistance, attributed to its compact structure and higher thread density. Charpy impact testing revealed that Kevlar/Polypropylene and Kevlar/Nylon composites achieved 204% and 75% increase in impact strength, respectively, compared to conventional Kevlar/Polyester composites. The Kevlar/Polypropylene composite excelled in tensile and impact strength, driven by stronger interfacial bonding, extended curing time, and ductility of polypropylene, making it promising for ballistic applications.

创新的3D混合编织和智能材料选择的弹道热塑性复合材料
采用基于多准则决策(MCDM)的智能材料选择技术开发了高性能热塑性复合材料,以确定弹道应用的最佳热塑性塑料。为了增强基体浸渍,设计了一种新型的混合3D编织技术,使增强材料和热塑性材料在预制过程中同时混合。这种方法消除了纺丝阶段密切混合的需要,降低了热塑性塑料在复合材料熔化过程中损坏增强纤维的风险。尼龙-6和聚丙烯通过这种智能选择过程,并结合凯夫拉高性能纤维制造。凯夫拉/聚丙烯预制体具有优异的透气性,由于其开放式结构,确保复合材料制造过程中树脂流动均匀。相比之下,凯夫拉/尼龙预成型由于结构紧凑和螺纹密度高,表现出更好的抗慢渗性能。Charpy冲击测试显示,与传统的凯夫拉/聚酯复合材料相比,凯夫拉/聚丙烯复合材料和凯夫拉/尼龙复合材料的冲击强度分别提高了204%和75%。凯夫拉/聚丙烯复合材料在拉伸和冲击强度方面表现出色,这得益于更强的界面结合、更长的固化时间和聚丙烯的延展性,使其在弹道应用方面前景广阔。
