Abstract

The structure and geometrical accuracy of injection-molded gears made of PA6, PA66 and PPA filled with glass fiber (30, 35 and 50%) were investigated. Using the AMI software, the injection mold cavity and the injection point distribution were simulated and the orientation of the glass fibers in the product was determined. SEM analysis of the gears fracture surfaces confirmed the good adhesion and dispersion of the glass fiber in the polymer matrix. However, the low accuracy class of injection-molded gears may indicate the need to optimize the injection process, which will be the subject of further research.

注塑复合材料齿轮的结构与几何精度

研究了PA6、PA66和PPA填充30%、35%和50%玻璃纤维的注塑齿轮的结构和几何精度。利用AMI软件对注射模型腔和注射点分布进行了模拟，确定了玻璃纤维在制品中的取向。齿轮断裂表面的SEM分析证实了玻璃纤维在聚合物基体中的良好粘附性和分散性。然而，注射成型齿轮的低精度等级可能表明需要优化注射工艺，这将是进一步研究的课题。
