Combination Automated Fibre Placement AFP

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.

自动化处理技术例如自动纤维铺放（AFP）或自动铺带（ATL）如今是众所周知的。这些程序仍有很大潜力取得更好的结果。在所提出的研究中，与自动纤维铺放的问题，然后提出了解决问题的方法。当铺设纤维复合材料时，预浸料坯之间通常会产生间隙。这些在复杂和双曲面上特别明显。美国航空航天研究所（AIAA）的一项研究表明，0.76 mm的间隙可使层压板的抗压强度降低27%。为了弥补这种生产方法不可避免的弱点，铺设了额外的纤维复合材料层，以提高部件的机械性能。这意味着组件将更重，生产成本更高。在拟议的研究中，一个具有无限纤维增强热塑性塑料的3D打印机被集成到一个移动的热塑性AFP头中。在将预浸料放置在模具上之后，通过传感器轮廓检测间隙。这些间隙是在3D打印机的帮助下用连续纤维增强塑料填充的。结合这两种方法，可以更均匀地生产组件。随后，由于避免了额外的层，部件被更快、更便宜甚至更轻地生产。
