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

在所需的研究项目中，将开发和研究一种三相材料;这种材料将在细丝水平上混合，除了热塑性基体外，还包括金属和非金属增强细丝，这些细丝将作为细丝插入。在半成品纺织品层面，流程优势--如流程短、加工时间短以及组件制造过程中出色的悬垂性--将与材料层面的可焊接性和多功能性相结合。因此，这类新材料的力学性能和潜力将通过实验和广泛的数值表征进行深入研究。该研究项目的另一个主要目标是开发和研究基于空气喷射和展开折叠技术的三相高度混合纤维混合复合材料的实现技术。所获得的知识和材料的理解，从金属长丝纱线的表面改性的杂交和固结过程和数值，纤维混合复合材料的微观力学建模，可以在未来使用，以实现复合材料定制的机械性能和专门可调的故障行为。

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.
