In a state where a gas barrier sheet ( ) having a gas barrier layer is held between a heat plate ( ) and a pressing plate, the gas barrier sheet is disposed between two molds together with a sub tank ( ) and a separator ( ) constituting attachment parts, the molds are then closed and a resin is injection-molded forming a resin layer ( ). A method for manufacturing a resin container by melt-adhering an intermediate molded product ( ) and another intermediate molded product ( ) constituting a pair therewith by heating with a heat plate ( ) thereafter, and a resin container manufactured by this manufacturing method.

Manufacturing method for a resin container

This invention relates to a method of manufacturing molded wooden products composed of a wooden body and a skin material. This method employs materials having long working life and enables simultaneous integral molding of the wooden body and the skin. The obtained molded wooden product has excellent characteristics.

Method of manufacturing a molded wooden product

A method for the manufacture of a fiber reinforced plastic structure, comprising the steps of winding a continuous long-staple fiber impregnated with a liquid resin around a plurality of winding jigs until the resultant bundle of resin impregnated fibers attains a predetermined thickness; setting rings tightly in place on the linear portions of the resin impregnated fiber bundle between the jigs; and moving the tightly set rings relative to the linear portions thereby wringing the resin impregnated fiber bundle and expelling bubbles entrapped within the fiber bundle.

Method for production of fiber reinforced plastic structure

A steering wheel core material of continuous filament FRP for vehicles which is made up of a ring, a boss positioned at the center of the ring, and spokes connecting the boss to the ring, said boss being integrally joined to a boss metal fitting. It is formed by winding resin-impregnated continous filaments in layer around the ring- and spoke-forming mold and the body of the boss metal fitting, with an elastic material interposed between the body of the boss metal fitting and the FRP.

Steering wheel core material

A core for a steering wheel made of a long fiber-reinforced resin in which a ring portion, a boss portion and a three spoke portions including a first spoke portion, a second spoke portion and a third spoke portion extending in a generally T-shaped configuration from the ring portion to the boss portion, are formed by bundles of continuous fibers reinforced with a resin. The cross-sectional area for the second spoke portion situated between the first spoke portion and the third spoke portion is made smaller than the cross-sectional area for the first spoke portion and the third spoke portion.

Core material for steering wheels made of long fiber-reinforced resin

A process for preparing a fiber reinforced plastic structure having points of branching, which comprises the steps of, positioning pins at points of branching in the structure and repeatedly hanging and repeatedly stretching a resin-impregnated strand of continuous long-staple fibers over and between said pins, thereby completing the structure of the points of branching.
