自动化加工技术，如自动光纤放置（AFP）或自动胶带铺设（ATL）是当今众所周知的。然而，这些方法仍然有很大的潜力来获得更好的结果，特别是对于大型和复杂的复合结构。在本实验工作中，展示了自动铺放光纤的间隙效应，并提出了克服这一缺陷的解决方案。这些间隙在复杂曲面和/或双曲面上特别明显，并降低了复合材料结构的力学性能。为了覆盖这种效应不可避免的薄弱区域，将多个纤维复合层相互叠加，以增加部件的机械性能。这反过来又使组件更重，生产成本更高。在这种新方法中，在模具上放置胶带后，通过轮廓传感器检测间隙。这些缝隙是在3D打印机的帮助下用碳连续纤维增强塑料填充的。通过结合3D打印和AFP技术，复合材料部件可以以更均匀的方式制造。随后，由于避免了额外的层，组件生产得更快，更便宜，甚至更轻。
Automated processing techniques such as automated fiber placement (AFP) or automated tape laying (ATL) are well known nowadays. However, there is still a lot of potential for these methods to achieve better results, especially for large and complex composite structures. In this experimental work, the gap effect with the Automated Fiber Placement is shown and a solution to overcome this drawback is presented. The gaps are particularly apparent on complex and/or double-curved surfaces and reduce the mechanical properties of the composite structure. In order to cover the unavoidable weak area of this effect, a plurality of fiber composite layers are laid on top of one another in order to increase the mechanical properties of components. This in turn makes the components heavier and more expensive to produce. In this new method, the gaps are detected by profile sensor after placement of the tape on the mold. The gaps are filled with the aid of a 3D printer with carbon continuous-fiber reinforced plastics. By combining the 3D printing and AFP technology, composite parts can be manufactured in a more homogeneous manner. Subsequently, the components are produced faster, cheaper and even lighter because of the avoidance of the additional layers.
