Simulation method, manufacturing method of preform base material, preform manufacturing method, simulation apparatus, preform base material, preform, fiber reinforced plastic molded body, and simulation program
The simulation apparatus simulates the behavior when shaping the reinforcing fiber base material into the shaping mold based on the shaping characteristics to obtain a first preliminary cut pattern and trims unnecessary portions from the first preliminary cut pattern , Simulating the behavior of shaping the reinforcing fiber base material on which the trimmed first preliminary cut pattern has been developed to obtain a second preliminary cut pattern and forming a notch in the second preliminary cut pattern , And simulating the behavior of shaping the reinforcing fiber base material on which the second preliminary cut pattern having the incision has been developed to obtain a third preliminary cut pattern and overlapping in the third preliminary cut pattern At least one of the regions is cut out and developed to generate a cut pattern for the preform.
