Abstract
Abstract An improved fiber composite including a first layer (18) having a plurality of elongate flexible fabric segments (16) for laying up on and conforming to an elongate irregularly shaped temporary support (10) to substantially cover support (10) and a plurality of continuous yarns (b 17) extending substantially the length of support (10). A second layer (26) includes a continuous yarn (20) wound peripherally upon the first layer (18) and oriented substantially orthogonally with the longitudinal yarns (17) of first layer (18). A method for manufacturing the fiber composite is also provided.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
77 words
An improved fiber reinforced composite, said fiber reinforcement comprising: a first layer comprising a plurality of elongate flexible fabric segments arranged together in an abutting side-by-side relationship defining an elongate irregularly shaped body shell form and having a plurality of continuous longitudinal yarns extending axially the length of each fabric segment, and a second layer comprising a continuous yarn wound peripherally upon said first layer and oriented substantially orthogonally with said longitudinal yarns of said first layer.
Claim 2
Dependent Claim
77 words
An improved fiber reinforced composite, said fiber reinforcement comprising: a first layer comprising a plurality of elongate flexible fabric segments arranged together in an abutting side-by-side relationship defining an elongate irregularly shaped body shell form and having a plurality of continuous longitudinal yarns extending axially the length of each fabric segment, and a second layer comprising a continuous yarn wound peripherally upon said first layer and oriented substantially orthogonally with said longitudinal yarns of said first layer.
Claim 3
Dependent Claim
83 words
The fiber composite in accordance with claim 1 further comprising one or more additional alternating layers of fabric segments and continuous yarn, each additional fabric segment layer being laid up on a wound continuous yarns layer for substantially covering said yarn layer and having a plurality of continuous longitudinal yarns extending axially the length of each fabric segment and each additional yarn layer being wound peripherally upon said additional fabric layer and oriented substantially orthogonally with said longitudinal yarns of said fabric layer.

Claim 7
Dependent Claim
14 words
The fiber composite in accordance with claim 5 wherein said resin matrix is carbonized.
Claim 8
Dependent Claim
14 words
The fiber composite in accordance with claim 5 wherein said resin matrix is graphitized.
