The manufacturing process of high pressure die casting offers a series mass production with near net shape design of light metal components. The lightweight construction material CFRP (carbon fiber reinforced plastic) is well established as a high-performance material for the production of highly durable and ultra-lightweight components. The combination of the two materials aluminum and CFRP is currently the focus of engineers to create lightweight structures. The specified aim of the first funding period was to combine the materials aluminum and thermoplastic CFRP into an intrinsic hybrid composite within a single, original manufacturing step. This aim has been successful achieved. The results show that it is not just possible to combine CFRP with aluminum using high pressure die casting. The tensile shear tests achieved a joint strength approximately in the range of current single lap adhesive bonds. Based on the results so far, new deepening question for the upcoming project phase could be defined. 1. Detailed characterization of the interface and development of process boundaries for the production of hybrid composite2. Investigation of the influence of different heat treatments and development of a heat treatment method tailored to the hybrid composite3. Optimization of the hybrid composite and development of design recommendationsThe results of the bond strength, which are in the range of structural adhesives, show that PEEK behaves similar to an adhesive. Further investigations in this area, including chemical analysis, could help to contribute that this novel technology could find application in other areas of joining technology as well.

高压压铸的制造过程提供了一系列的大规模生产，具有轻金属部件的近净形设计。轻质建筑材料CFRP（碳纤维增强塑料）是一种高性能材料，可用于生产高耐用性和超轻质部件。铝和CFRP这两种材料的结合是目前工程师们创造轻质结构的重点。第一个供资期的具体目标是在一个单一的原始制造步骤中将铝和热塑性CFRP材料联合收割机组合成一种内在的混合复合材料。这一目标已经成功实现。结果表明，不可能仅仅使用高压压铸将CFRP与铝联合收割机结合。拉伸剪切试验实现了约在当前单搭接粘合剂粘结范围内的接头强度。根据迄今为止的结果，可以为即将到来的项目阶段确定新的深化问题。1.混合复合材料生产的界面的详细表征和工艺边界的开发2.研究不同热处理的影响，并开发适合混合复合材料的热处理方法3。混杂复合材料的优化和设计说明的发展粘结强度的结果，这是在结构胶粘剂的范围内，表明PEEK的行为类似于胶粘剂。在这一领域的进一步研究，包括化学分析，可能有助于促进这种新技术也可以在连接技术的其他领域中找到应用。
