Automated fibre placement (AFP) of thermoplastic composites has been reaching a high efficient and technological level in the last years. In situ consolidation (ISC) process involves cost reduction since extra autoclave cycle is not required. A good control of the temperature and pressure during the lamination is mandatory to achieve a good consolidation without thermal degradation for the manufacturing of high quality parts. Due to the manufacturing set-up, temperature monitoring is limited to infrared thermographic cameras and superficial measurements. Within this context, Fibre Bragg grating (FBG) sensors emerged as a potential device for thermal history monitoring in real-time. An investigation was carried out by using different FBG sensors for process monitoring of thermoplastic ISC. In this study, the sensors were embedded inside CF/PEEK thermoplastic samples and the lamination process was subsequently monitored. Also, a thermal model was created in order to obtain ...

使用FBG传感器实时监控热塑性塑料自动层压的热历史，并验证过程模型

近年来，热塑性复合材料的自动纤维铺放（AFP）已达到高效和技术水平。原位固结（ISC）过程可降低成本，因为不需要额外的高压灭菌周期。层压期间必须对温度和压力进行良好的控制，以实现良好的固结性而不会因制造高质量零件而发生热降解。由于生产设置的原因，温度监控仅限于红外热像仪和表面测量。在这种情况下，光纤布拉格光栅（FBG）传感器成为实时监控热历史的潜在设备。通过使用不同的FBG传感器进行热塑性ISC的过程监控进行了调查。在这个研究中，将传感器嵌入CF / PEEK热塑性塑料样品中，然后监控层压过程。此外，创建了一个热模型，以获得...
