  • Means for molding fiber reinforced composite tube
    Patent number: 3999912
    Abstract: A fiber reinforced composite tube is molded by applying an annular, liquid-resin-impregnated layer of reinforcing fibers to a cylindrical mold or mandrel; placing in contact with the exposed surface of the fiber-resin layer a compression sleeve which is split lengthwise to permit circumferential contraction or expansion of the sleeve into pressurizing relation with the layer; pressurizing the compression sleeve with fluid pressure to compress the fiber-resin layer and thereby compact the reinforcing fibers and expell entrapped air and excess resin from the layer; and curing the resin while the fiber-resin layer is so compressed.
    Type: Grant
