Description
Summary: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.
