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.

在所需的研究项目中，将开发和研究一种三相材料；该材料将在细丝水平上进行混合，除热塑性基质外还包含金属和非金属增强细丝，该基质将作为在纺织半成品层面，流程优势（例如较短的流程和加工时间以及部件制造过程中出色的悬垂性）将与材料层面的可焊性和多功能性相结合。该研究项目的另一个主要目标是开发和研究用于实现基于三相、高度混合的纤维混合复合材料的技术。所获得的知识和材料理解，从金属长丝纱线的表面改性到混合和固结过程以及纤维混合复合材料的数值、微机械建模。未来将实现具有定制机械性能和特别可调节失效行为的复合材料。
