探讨了自动铺带工艺过程中相邻铺层界面间的贴合形成机制,将铺层界面间贴合过程建模为树脂补片在平行板之间挤压流动从而浸润界面的过程。指出在树脂流体黏度一定的情况下,树脂对界面浸润效果越好,则界面贴合能力越强。利用流体力学理论推导出树脂流体对界面浸润效果的计算公式,并分析了铺放压力、铺放速度等因素对浸润效果以及贴合能力的影响,提出以剥离力作为量化铺层间贴合能力的指标。在自行研制的自动铺带工艺参数实验平台上进行了一系列实验,实验结果表明,铺层间贴合能力随铺放速度增大而变差,随铺放压力、模具温度、压辊半径增大而变强,这一规律验证了所提出的树脂流体对界面浸润效果计算公式的正确性。
The formation mechanism of bonding between adjacent layers in the automatic tape laying process was discussed. The bonding process between the layers was modeled as the process of squeezing and flowing the resin sheet between parallel plates to infiltrate the interface. It is pointed out that when the viscosity of the resin fluid is constant, the better the wetting effect of the resin on the interface is, the stronger the interface bonding ability is. Based on the theory of fluid mechanics, the formula of resin fluid’s infiltration effect on interface was deduced. The influence of deposition pressure and laying velocity on wetting effect and bonding ability was also analyzed. index of. A series of experiments were carried out on a self-developed automatic paving process parameters experimental platform. The experimental results show that the laminating ability between the layers decreases with the increase of laying speed. With the increase of laying pressure, mold temperature, Large and strong, this rule validates the proposed resin fluid infiltration effect on the interface of the correctness of the formula.
