Abstract
Abstract A fabric tube (2) is reinforced in a non-uniform manner by one or more elongate members (6) extending longitudinally within the material of the fabric. In a preferred embodiment elongate carbon fibre tows extend within a glass fibre fabric. The reinforced tube may be used where non-uniform reinforcement is desirable in order to achieve a low strenght/weight ratio - for example in tennis recquets.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
70 words
A reinforced fabric tube (2) having at least one elongate member (6) extending substantially longitudinally and within the fabric of the tube so as to provide non-uniform reinforcement of the fabric circumferentially of the tube, and wherein said at least one elongate member (6) and/or the material forming said fabric has an elastic modulus of at least 50 giga Pascals.and/or has a tensile strength of at least 2 giga Pascals.
Claim 2
Dependent Claim
70 words
A reinforced fabric tube (2) having at least one elongate member (6) extending substantially longitudinally and within the fabric of the tube so as to provide non-uniform reinforcement of the fabric circumferentially of the tube, and wherein said at least one elongate member (6) and/or the material forming said fabric has an elastic modulus of at least 50 giga Pascals.and/or has a tensile strength of at least 2 giga Pascals.
Claim 3
Dependent Claim
14 words
A tube according to Claim 1, comprising a plurality of said elongate members (6).
Claim 4
Dependent Claim
28 words
A tube according to Claim 2 wherein at least one of the members (6) is of a different type from the others thereby to provide said non-uniform reinforcement.
Claim 5
Dependent Claim
22 words
A tube according to Claim 2 or 3, wherein the concentration of the members (6) is non-uniform circumferentially of the tube (2).
Claim 6
Dependent Claim
32 words
A tube according to Claim 4, wherein two circumferentially opposed portions of the tube (2) have a higher concentration of said elongate members (6) than the remaining portions of the tube (2).
Claim 7
Dependent Claim
26 words
A tube according to any preceding Claim, comprising at least one further elongate member (6') that extends spirally within and along the fabric of the tube(2).
Claim 8
Dependent Claim
43 words
A tube according to any preceding Claim, wherein the material of the fabric and/or of said elongate member (6,7) comprises one or more of glass fibre, carbon fibre, boron fibre, an aromatic polyamide fibre, PBI, silicon carbide, aluminium oxide, metal filament, or wire.
Claim 9
Dependent Claim
19 words
A tube according to any preceding Claim wherein the fabric comprises a braid or a weave or a knit.
Claim 10
Dependent Claim
38 words
A tube according to any preceding Claim, wherein the reinforced fabric is embedded or impregnated in a matrix (12) that preferably comprises one or more of an elastomer, thermosetting material, concrete, resin, metal alloy, thermoplastic, ceramic and glass.
