  • Automobile bumper constructed of fused resin members
    Patent number: 5178425
    Abstract: An automobile bumper comprises a bumper face and a bumper beam constructed of members molded of thermoplastic resin. The bumper beam includes at least two members of thermoplastic resin having flanges for forming beam flanges together when the members are fused to each other, the beam flanges being fused to an inner surface of the bumper face. An FRP sheet is continuously heated in an atmosphere having a temperature successively lowered from a temperature higher than a resin melting temperature at which a resin of the FRP sheet is melted so that the entire FRP sheet is increased through successive heating stages to a temperature between the resin melting temperature and a resin degradation temperature at which the resin of the FRP sheet is degraded.
    Type: Grant
    Filed: September 3, 1991
    Date of Patent: January 12, 1993
