The high volume production of carbon fibre reinforced plastics needs cost efficient and robust processes. This paper investigates the influence of local textile variation on flow front progression in resin transfer moulding (RTM). To quantify the textile variation, the textile has been tested with laser triangulation, to achieve the thickness profile map of the flat textile preform. This preform is placed in a transparent flow visualisation tool and an oil is injected into the mould via two different flow channel distribution systems. The flow front progression of the fluid is continuously measured from both sides with two cameras. Furthermore, to demonstrate the influence of defects like folds from the draping process on the local filling behaviour, the textile is prepared with an artificial fold, made of additional non-crimp fabric (NCF) strips. The results show how different defects in the textile influence the local filling behaviour and how the additional flow channel distribution system can decrease the effect of these defects.

碳纤维增强塑料的大量生产需要经济高效且坚固的工艺。本文研究了局部纺织品变化对树脂传递模塑（RTM）中流动前沿发展的影响。为了量化纺织品变化，已对纺织品进行了激光三角测量，以获取扁平纺织品预成型件的厚度轮廓图。将该预成型件放置在透明的流动可视化工具中，并通过两个不同的流动通道分配系统将油注入模具中。使用两个摄像头从两侧连续测量流体的流动前沿进程。此外，为了证明诸如悬垂过程中的褶皱之类的缺陷对局部填充行为的影响，该纺织品采用人工褶皱制成，该褶皱由附加的非卷曲织物（NCF）条制成。
