Abstract

The quality of a braided preform significantly impacts composite performance and its manufacturing control is paramount. However, predicting the braiding process, especially for irregular composite shapes, poses challenges. To tackle the problem, this paper proposes a numerical modeling method based on the software Abaqus. It is firstly utilized to declare the dynamic stabilization mechanism of the braiding progress on a circular and straight mandrel, validating the deposit plane position and braiding angle against theoretical results. The stable deposit plane position is then used to guide the initial placement of the mandrels with irregular geometries, such as complex, varying profile and curved centerline. Based on the method, uniform braiding configurations are obtained numerically, with their patterns discussed via comparisons with results from mismatched mandrel placements. Fiber distribution rules on different irregular geometric features have also been investigated. The method proposed can guide the mandrel control and improve the braiding quality of irregular composite preforms during manufacturing.

利用有限元法研究编织工艺对复合材料预成型质量的影响

编织预型件的质量对复合材料的性能有重大影响，因此其制造控制至关重要。然而，预测编织过程，尤其是不规则复合材料形状的编织过程，是一项挑战。针对这一问题，本文提出了一种基于 Abaqus 软件的数值建模方法。首先，利用该方法声明了在圆形和直线心轴上编织过程的动态稳定机制，并根据理论结果验证了沉积平面位置和编织角度。然后，利用稳定的沉积平面位置来指导具有不规则几何形状（如复杂、不同轮廓和弯曲中心线）的心轴的初始放置。根据该方法，可以通过数值计算获得均匀的编织配置，并通过与不匹配芯棒放置结果的比较讨论其模式。此外，还研究了不同不规则几何特征上的纤维分布规则。所提出的方法可以在制造过程中指导心轴控制，提高不规则复合材料预型件的编织质量。
