摘要

摘要: 为研究铺放工艺参数对复合材料预浸料丝束曲线铺贴质量的影响规律及作用机制，首先自主设计并搭建了可模拟铺丝机曲线铺贴运动的试验平台，进行了变铺放工艺参数与变铺放半径的预浸料丝束曲线铺贴试验。通过测量计算有效贴合长度比、褶皱角度及曲率半径比，并结合变铺放工艺参数的单因素剥离试验对铺放质量进行了表征。结果表明：曲线铺贴质量与预浸料丝束黏结力及弯曲刚度密切相关；随铺放温度、压力和张力增大、铺放速率减小，丝束黏结力上升，曲线铺贴质量提高；铺放温度升高引起的丝束弯曲刚度下降可提升曲线铺贴准确性，但过高的铺放温度会导致丝束黏性下降，曲线铺贴缺陷显著；铺放张力会改变丝束的受力状态，进而影响曲线铺贴路径的准确性；此外，曲线铺贴半径越小，铺放质量对工艺参数的变化越敏感。

Abstract: In order to study the effect and mechanism of laying process parameters on the curve trajectory placement quality of prepreg tow, an automated fiber placement simulation test platform was designed and built firstly, and the test of curve trajectory placement was carried out by changing the laying process parameters and laying radius. The laying quality was represented by the measurement and calculation of effective tack width ratio, wrinkle angle and curvature radius ratio and also the results of peeling test of variable laying process parameters. The results show that the curve trajectory placement quality is closely related to the tack and bending stiffness of prepreg tow. With the increase of laying temperature, pressure and tension and the decrease of laying velocity, the tack of prepreg tow increases and the curve trajectory placement quality is improved. Due to the increase of laying temperature, the bending stiffness of the prepreg tow decreases, which can improve the accuracy of laying. However, excessive temperature will cause the tack of the prepreg tow to decrease, make the defect of curve placement obvious. The laying tension will change the stress state of the prepreg tow, thus affecting the accuracy of the laying path. In addition, the smaller the curve placement radius is, the more sensitive the placement quality is to the change of process parameters.
