通过对自动铺放成型工艺的分析，探索了自动铺带成型过程中预浸料温度对复合材料黏性的影响规律。对影响预浸料温度的热风温度和铺放速度两个因素进行了研究，从理论上建立了热风加热温度和铺放速度与预浸料温度之间的关系，提出了控制预浸料温度的具体实施方案，指导自动铺带成型过程。根据双马树脂预浸料黏度和温度曲线，分别在不同的热风温度和铺放速度条件下进行实验，得到在热风温度为90℃、铺放速度为10-20m／min时，预浸料黏度满足铺覆性要求，验证了预浸料热风温度和铺放速度对复合材料制品质量的影响，为自动铺带工艺提供参考。
By the analysis of automated tape laying （ATL） process, the viscosity- temperature relationship of the composite prepregs was investigated. By the research on hot-air temperature and placement rate, which are two main factors on the prepregs temperature, the theoretic relationship between hot-air temperature and placement rate was examined, and then the controlling method of prepregs temperature was proposed to guide the ATL manufacturing. Finally, according to the viscosity- temperature curve of the bismaleimide resin prepregs, the experiments were conducted under different hot-air temperatures and placement rates. The results show that the viscosity of the prepregs agrees with the processing demand when the hot-air temperature is set at 90 ℃ and the placement rate is about 10 - 20 m/min. The research work indicates the influence on the composites structure, caused by prepregs hot-air temperature and placement rate, which will be helpful for the ATL process.
