Automated Tape Placement (ATP) technology is one of the processes that is used for the production of the thermoplastic composite materials. The ATP process is complex, requiring multiple melting/crystallization cycles. In the current paper, laser-assisted ATP was used to manufacture two thermoplastic composites (IM7/PEEK and AS4/PA12). Those specimens were compared to specimens that were made of thermoset polymeric composites (IM7/8552) manufactured while using a standard autoclave cycle. In order assess the quality, void content, fibre distribution, and fibre misalignment were measured. After manufacturing, specimens from the three materials were assessed using optical microscopy and computed tomography (CT) scans. The results showed that, as compared to the thermoset composites, thermoplastics that are manufactured by the ATP have a higher amount of voids. On the other hand, manufacturing using the ATP showed an improvement in both the fibre distribution inside the matrix and the fibre misalignment.
自动铺带（ATP）技术是用于生产热塑性复合材料的工艺之一。ATP工艺复杂，需要多个熔化/结晶循环。在当前论文中，激光辅助ATP被用于制造两种热塑性复合材料（IM7/PEEK和AS4/PA12）。将这些试样与使用标准热压罐工艺制造的热固性聚合物复合材料（IM7/8552）制成的试样进行比较。为了评估质量，测量了孔隙率、纤维分布和纤维排列不齐情况。制造完成后，使用光学显微镜和计算机断层扫描（CT）对这三种材料的试样进行评估。结果表明，与热固性复合材料相比，通过ATP制造的热塑性材料具有更高的孔隙率。另一方面，使用ATP制造在基体内部的纤维分布和纤维排列不齐方面都有改善。
