초록 ▼

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.

대표청구항 ▼

The method of molding a fiber-reinforced composite tube comprising the steps of: using a mold element having a peripheral molding surface about a central axis of the element; applying to said molding surface an annular liquidresin impregnated layer of reinforcing fibers; placing a compression sleeve in contact with an exposed side of said fiber-resin layer, said compression sleeve being longitudinally split so that the peripheral length of said sleeve can change with pressure and which sleeve is releasable from said resin; urging said compression sleeve against said fiber-resin layer by gaseous or fluid pressure, in such a way as to cause a change in the peripheral length of said sleeve by sliding one portion of said sleeve upon another portion of said sleeve, to compress the layer between said sleeve and mold element and thereby compact the reinforcing fibers in the layer; and curing the resin in said layer with heat while the layer is so compressed, and removing said sleeve from said layer and said layer from said mold element.
