GLASS FIBER LENGTH DISTRIBUTION DERIVATION APPARATUS, PROGRAM FOR DERIVING GLASS FIBER DISTRIBUTION AND RECORDING MEDIUM FOR DERIVING GLASS FIBER DISTRIBUTION

摘要

Provided is a technique for predicting, with a high accuracy, the fiber length distribution of glass fibers in a resin molding obtained by kneading a thermoplastic resin and glass fiber bundles together in an extruder and molding the kneaded mixture. The present invention pertains to a glass fiber length distribution derivation apparatus for deriving the fiber length distribution of glass fibers in a resin molding obtained by kneading a thermoplastic resin and glass fiber bundles together in an extruder and molding the kneaded mixture, wherein the fiber length distribution is derived by regarding the quotient obtained by dividing the temporal distribution of shear stress acting on each tracer particle by (Qbeta/Nsgamma) as the temporal distribution of shear stress acting on each glass fiber. The temporal distribution of shear stress acting on each tracer particle is determined by a particle tracking method.
