项目摘要

Automated processing techniques such as Automated Fiber Placement (AFP) or Automated Tape Laying (ATL) are well known nowadays. There is still much potential in these procedures to achieve better results. In the proposed research, the problem with the Automated Fiber Placement is addressed and then presented the solution to the problem. The gaps between the prepreg are often created when the fiber composite materials are laid down. These are particularly apparent on complex and double-curved surfaces. A study by the American Institute of Aeronautics and Astronautics (AIAA) has shown that a gap of 0.76 mm can reduce the compressive strength of the laminate up to 27%. In order to cover the unavoidable weak point of this production method, additional fiber composite layers are laid in order to increase the mechanical properties of components. This means the components will be heavier and more expensive to produce. In the proposed research, a 3D printer with an endless fiber-reinforced thermoplastic is integrated into a mobile thermoplastic AFP head. After placement the Prepreg on the mold, the gaps are detected by a sensor profile. The gaps are filled in with the aid of a 3D printer with continuous-fiber reinforced plastics. In combination of the two methods, the components can be produced more homogeneously. Subsequently the components are produced faster, cheaper and even lighter because of the avoidance of the additional layer.

如今，自动化处理技术（例如自动化光纤放置（AFP）或自动胶带铺设（ATL））如今已知。这些程序仍然有很大的潜力来取得更好的结果。在拟议的研究中，解决了自动化纤维放置的问题，然后提出了解决问题的解决方案。在放置纤维复合材料时，通常会产生预处理之间的差距。这些在复杂和双弯曲的表面上尤为明显。美国航空和宇航学研究所（AIAA）的一项研究表明，0.76毫米的间隙可以降低层压板的抗压强度高达27％。为了覆盖这种生产方法的不可避免的弱点，铺设了其他纤维复合层，以增加组件的机械性能。这意味着组件将更重，更昂贵。在拟议的研究中，将带有无数纤维增强热塑性的3D打印机集成到移动热塑性AFP头部。放置后，预处理在模具上，传感器轮廓检测到间隙。这些间隙充满了3D打印机，并带有连续纤维增强塑料。结合两种方法，可以更均匀地产生组件。随后，由于避免了额外的层，这些组件的产生速度更快，更便宜，更轻。
