摘要/Abstract

摘要：

针对波浪形弯曲流道浸渍模具分析了纤维束在模具内的受力做功情况，基于能量守恒原理构建了包含工艺参数与设备结构参数的模具内纤维束展宽模型。利用实验室自行设计的波浪形弯曲流道浸渍模具，探究了生产工艺参数与设备结构参数对模具内纤维束展开宽度的影响。结果表明，工艺参数对纤维束展宽影响较大，其中牵引张力是主要影响因素；设备结构参数在一定程度上对展宽也有所影响，模型能够有效预测纤维束在模具内浸渍阶段的展开宽度，为控制和优化纤维束在模具内的展宽过程提供了理论依据。

Abstract:

The work done by a fiber bundle in the mold was analyzed for the wavy curved runner impregnation mold， and the fiber bundle broadening model including process and equipment structure parameters was constructed according to the principle of energy conservation. The influence of process and structural parameters on the width of the fiber bundle in the mold was explored by using the wavy curved runner impregnation mold designed in the laboratory. The results indicated that the process parameters generated a great influence on the fiber bundle broadening. Among these parameters， the traction tension was the main influencing factor， and the equipment structure parameters also had an impact on the width expansion to a certain extent. The model can effectively predict the unfolding width of the fiber bundle in the mold impregnation stage， which provides a theoretical basis for controlling and optimizing the fiber bundle broadening process in the mold.

Key words: fiber broadening, melt impregnation, prepreg tape, conservation of energy
