MULTIPLE GLASS FIBER BONDED HIGH-STRENGTH PLASTIC BACK BEAM

摘要

PROBLEM TO BE SOLVED: To provide a multiple glass fiber bonded high-strength plastic back beam for attaining the uniform dispersion of collision performance while maintaining high-strength physical properties as they are.;SOLUTION: A high-strength bumper back beam of a plastic material manufactured of a glass thermoplastic resin is composed of a first fiber resin layer of compounding long fiber or short fiber and a thermoplastic resin and a second fiber resin layer of compounding continuous fiber and the thermoplastic resin, and manufactured so as to prevent the long fiber or the short fiber of the first fiber resin layer from infiltrating between the continuous fibers of the second fiber resin layer through its interface surface when heating and bonding the first fiber resin layer and the second fiber resin layer, and characterized by further including a resin film layer in the interface surface between the first fiber resin layer and the second fiber resin layer, preventing interlayer separation by bonding the first and second fiber resin layers, and preventing the long fiber or the short fiber of the first fiber resin layer from infiltrating between the continuous fibers of the second fiber resin layer.;COPYRIGHT: (C)2012,JPO&INPIT
