项目摘要

The trend towards lightweight construction in automotive engineering contributes significantly to environment protection by reducing pollutant emissions and by conserving resources. However, this development causes additional effort and higher expense in vehicle manufacturing, because new materials or, respectively, new material combinations require adapted production and processing methods. Varied combinations of metallic and fibre-based structures (GRP-/ CFRP components) presuppose convenient joining methods.In this context, the objective of this research project is the development of an innovative joining method for combining sheet metals with CFRP structures. The target of the proposed project is motivated by the requirement for such methods to prevent any damage of the used textile fibre structures during the joining process. Based on the semi-solid forming technology, the new joining process is to be developed to create a material integrated bond between fibres and metallic components.Basic experiments, described in this research proposal, have already shown the technical feasibility of this new type of joining technique. The research work to be carried out comprises the usage of different sheet alloys: The combinations steel-aluminium, aluminium-aluminium and steel-steel are to be joined reliable with internal carbon textiles. Subsequently, the quality of the produced hybrid structure is to be analysed by optical and mechanical examinations and, additionally, the reactions between the sheet metals or, respectively, between fibres and sheet metals have to be investigated.Furthermore, the new composite is to be numerically modelled by using the software ANSYS. Fluid dynamics and structure-mechanical processes are to be calculated by CFD and CSM codes. In this way, the infiltration of the rovings can be simulated. Based on these results, it should be possible to perform calculations of the composites´ strengths. In this way, the project is to provide evidence that the quality of manufactured connections and related to that the required process parameters can be calculated prior to the joining process.

汽车工程中轻巧建设的趋势通过减少污染物排放和保存资源来对环境保护产生重大贡献。但是，这种开发会导致额外的努力和更高的车辆制造费用，因为新材料或新材料组合需要适应的生产和加工方法。金属和基于纤维的结构（GRP-/ CFRP组件）的各种组合前提是方便的连接方法。在这种情况下，该研究项目的目的是开发一种创新的连接方法，用于将表金属与CFRP结构相结合。拟议项目的目标是由此类方法的要求，以防止在联接过程中损坏所使用的纺织纤维结构的任何损害。基于半固体形成技术，将开发新的加入过程，以在纤维和金属组件之间建立材料集成键。该研究建议中描述的基本实验已经显示了这种新型连接技术的技术可行性。要补偿不同纸合金使用的研究工作：组合钢铝，铝 - 铝和钢钢的组合将与内部碳纺织品一起可靠。随后，将通过光学和机械分析产生的杂种结构的质量。必须研究检查金属或纤维和薄板之间的薄板金属之间的反应。FURTHERMORE将使用软件ANSYS对新复合材料进行数值建模。流体动力学和结构机械过程应通过CFD和CSM代码计算。通过这种方式，可以模拟漫游的渗透。基于这些结果，应该可以对组成强度进行计算。通过这种方式，该项目是提供证据表明，制成的连接的质量以及与所需的过程参数可以在加入过程之前计算的。
