摘要研究了纤维弯曲取向和厚度分布对电沉积树脂模塑碳纤维增强塑料(CFRP)模式阻尼的影响。定制纤维贴片(TFP)被用于制造具有连续曲线路径或变轴向性能的碳纤维(CF)预制件。利用比阻尼力(SDC)的概念计算了复合材料的阻尼力。利用粒子群优化算法(PSO)对纤维形状进行了优化，使第一模式的SDC达到最大。结果表明，与几种单向纤维形状相比，优化的纤维形状改善了一阶固有频率和模式SDC。
Abstract The effect of both curvilinear fiber orientation and thickness distribution on modal damping of carbon fiber reinforced plastics (CFRP) fabricated by electrodeposition resin molding (ERM) was investigated. Tailored fiber placement (TFP) was used to manufacture carbon fiber (CF) performs with continuous curvilinear fiber paths or variable-axial properties. The damping of composites was calculated using the concept of specific damping capacity (SDC). Fiber shapes was optimized to maximize the first modal SDC using particle swarm optimization (PSO). As a result, the optimum fiber shape improves both the first natural frequency and modal SDC in comparison with several unidirectional fiber shapes.
