Steel/highperformance/thermoplastic fibre-hybrid composites dispersed at the filament level with tailored mechanical properties and high structural integrity

在期望的研究项目中，将开发和研究三相材料；这种材料将在长丝水平上混合，除了作为长丝插入的热塑性基质外，还包括金属和非金属增强长丝。在半成品纺织产品的层面上，程序上的优势——如短的流动路径和加工时间，以及组件制造过程中出色的可垂性——将与材料层面的可焊性和多功能性相结合。因此，这种新型材料的力学性能和潜力将通过实验和广泛的数值表征来彻底研究。该研究项目的另一个主要目标是开发和研究基于喷气和伸展折叠技术的三相、高度混合的纤维混合复合材料的实现技术。所获得的知识和对材料的理解，从金属长丝的表面改性到杂交和固结过程，以及纤维混合复合材料的数值、微观力学建模，可以在未来用于实现具有定制机械性能和特定可调失效行为的复合材料。

Within the desired research project, a three-phase material will be developed and investigated; this material will be hybridised at the filament level and consist of metallic as well as non-metallic reinforcement filaments in addition to a thermoplastic matrix, which will be inserted as filaments. At the level of the semi-finished textile product, procedural advantages – such as short flow paths and processing times as well as excellent drapeability during component manufacturing – will be combined with weldability and multifunctionality at the material level. Therefore, the mechanical properties and potential of this new class of materials will be thoroughly investigated by means of experimental and extensive numerical characterizations. Another main objective of this research project is the development and investigation of technologies for the realization of three-phase, highly hybridised fibre-hybrid composites based on air-jet and spread-folding technology. The gained knowledge and material understanding, ranging from the surface modification of metallic filament yarns to the hybridization and consolidation processes and the numerical, micromechanical modeling of fibre-hybrid composites, can be used in future to achieve composites with tailored mechanical properties and a specifically adjustable failure behaviour.
