Abstract
Abstract A method for fabricating fiber reinforced articles. A plurality of elongated fibers are formed into a bundle and impregnated with a resin matrix material. The impregnated bundle is encapsulated in a resilient tube and longitudinal tension is applied to the tube to align and consolidate the fibers in the bundle while the resin cures, after which the tube is removed from the bundle.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
33 words
A method in accordance with claim 1 wherein after said resin is partially cured, said tube and bundle are then deformed transversely of the axis thereof followed by full curing of said resin.
Claim 2
Dependent Claim
24 words
A method in accordance with claim 1 wherein, in formation of said bundle, said fibers are disposed to at least partially enclose a core.
Claim 3
Dependent Claim
29 words
A method in accordance with claim 3 wherein said core is composed of a fusible alloy material and wherein said core is melted from said bundle after curing thereof.
Claim 4
Dependent Claim
25 words
A method in accordance with claim 1 wherein, during formation of said bundle, said fibers are disposed to enclose a centrally located, longitudinally disposed core.
Claim 5
Dependent Claim
24 words
A method in accordance with claim 2 wherein, during formation of said bundle, said fibers are disposed to at least partially enclose a core.
Claim 6
Dependent Claim
30 words
A method in accordance with claim 6 wherein said core is composed of a fusible alloy material and wherein said core is melted from said bundle after full curing thereof.
Claim 7
Independent Claim
94 words
A method of fabricating fiber reinforced articles comprising the steps of: encapsulating a resin impregnated bundle of elongated fibers in a resilient tube having a circular cross section and a length greater than the length of the impregnated bundle of fibers to provide unfilled tubular ends; clamping the unfilled ends of the resilient tube; at least partially curing the resin while applying longitudinal tension to said tube through the end clamps to elongate said tube which applies radial compression for consolidation of the fibers in said bundle; and removing said tube from said bundle.
