GLASS FIBER LENGTH DISTRIBUTION DERIVING DEVICE, GLASS FIBER DISTRIBUTION DERIVING PROGRAM AND GLASS FIBER DISTRIBUTION DERIVING RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a technology for highly accurately predicting the distribution of the fiber length of glass fiber in a resin mold molded by kneading a thermoplastic resin and a glass fiber bundle by an extruder.SOLUTION: The glass fiber length distribution deriving device derives the distribution of the fiber length of the glass fiber in the resin mold molded by kneading the thermoplastic resin and the glass fiber bundle by the extruder. The device derives the glass fiber length distribution by regarding a value of dividing the time distribution of shearing stress of acting on respective tracer particles derived by a particle tracking method by (Q/Ns), as the time distribution of shearing stress of acting on the respective glass fibers.
