Laser-assisted tape placement and tape winding represent the most advanced automated manufacturing technologies for thermoplastic composites. It is important to accurately predict the complete thermal history of the manufacturing process, on which many properties of the product are strongly dependent, such as interlaminar bonding strength and crystallization. In this article, a nonlinear two-dimensional transient heat transfer model was established in ANSYS APDL, and a new temperature closed-loop controlled near-infrared laser heat source was described. Most importantly, the thermal contact pairs were introduced following the activation of elements, and the value of interlaminar thermal contact resistance was obtained by fitting an independent experiment and finite element analysis, which greatly optimized the heat transfer process in the direction of thickness. The thermal model was verified by infrared cameras and an online temperature measuring system based on thermocouples. The results of thermal history are in good agreement with the experiment, which were input into the crystallization kinetics model to predict the evolution and distribution of crystallinity in the laser-assisted tape winding process. The calculated results are coincident with the differential scanning calorimeter test very well, and the crystallinity was about 17% higher than that before manufacturing.

激光辅助的胶带放置和胶带缠绕是热塑性复合材料最先进的自动化制造技术。准确预测制造过程的完整热历史很重要，产品的许多特性在很大程度上取决于该过程，例如层间粘合强度和结晶度。本文在ANSYS APDL中建立了非线性二维瞬态传热模型，并描述了一种新型的温度闭环控制的近红外激光热源。最重要的是，在元件激活后引入了热接触对，并通过独立实验和有限元分析获得层间热接触电阻的值，这极大地优化了沿厚度方向的传热过程。通过红外热像仪和基于热电偶的在线温度测量系统对热模型进行了验证。热历史的结果与实验吻合得很好，将其输入到结晶动力学模型中，以预测在激光辅助带缠绕过程中结晶度的演变和分布。计算结果与差示扫描量热仪测试非常吻合，并且结晶度比制造前高约17％。将其输入到结晶动力学模型中，以预测在激光辅助带缠绕过程中结晶度的演变和分布。计算结果与差示扫描量热仪测试非常吻合，并且结晶度比制造前高约17％。将其输入到结晶动力学模型中，以预测在激光辅助带缠绕过程中结晶度的演变和分布。计算结果与差示扫描量热仪测试非常吻合，并且结晶度比制造前高约17％。
