论文摘要
玻璃织物增强热塑性（GFRT）构成了一类复合材料，由于其重量低，易于生产和机械性能，它们特别适合汽车结构。但是，在制造过程中，在形成预制的层压板期间，可能会发生玻璃织物以及聚合物基质中的缺陷，这可能会损害组件的安全性或寿命。因此，在GFRT中检测出生产监测的缺陷以及对缺陷形成/进化的深刻理解对于群众生产至关重要。在这里，我们在实验上证明，可以通过基于边缘弹片原理可靠地检测到某种类型的缺陷（即局部纤维移位）。
Glass fabric reinforced thermoplastic (GFRT) constitutes a class of composite materials that are especially suited for automobile construction due to their combination of low weight, ease of production and mechanical properties. However, in the manufacturing process, during forming of prefabricated laminates, defects in the glass fabric as well as in the polymer matrix can occur, which may compromise the safety or the lifetime of components. Thus, the detection of defects in GFRTs for production monitoring and a deep understanding of defect formation/evolution is essential for mass production. Here, we experimentally demonstrate that a certain type of defects (i.e., local fiber shifts), can be detected reliably by X-ray scattering based on the edge-illumination principle.
