  • Method of covering a profiled surface of a base member with a sheet by using bonding under vacuum, and a sheet suitable for use in the method
    Patent number: 6265044
    Abstract: A vacuum covering method for covering a profiled surface of a base member with a sheet by effecting bonding between the sheet and the base member under vacuum, wherein the base member has a multiplicity of spaced vacuum grooves extending across the profiled surface. When air is evacuated from the vacuum grooves, the sheet is drawn by vacuum or suction down onto the profiled surface. The base member is injection-molded of synthetic resin and undergoes thermal shrinkage when it becomes cool after molding. With the vacuum grooves provided in the profiled surface, thermal shrinkage is distributed uniformly over the entire area of the profiled surface and does not generate shrink mark which may form a depression on a front surface of the sheet bonded to the base member.

  • 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.
