Abstract
Abstract A fabric made up of thermoplastic fibers and of reinforcing fibers, comprising, in a superposed manner, at least two tissues (1, 4) joined firmly to each other, in which in order to obtain a thermoplastic fabric, at least one (1) of the superposed tissues is dedicated to reinforcement and comprises predominantly fibers (2, 3) of reinforcing material, and at least one other (4) of the superposed tissues constitutes a thermoplastic matrix and comprises predominantly fibers (5, 6) of thermoplastic resin, while the gap (8) between a reinforcing tissue (1) and an adjacent thermoplastic tissue (4) is free of any inserted material other than that (7) used to join these two tissues firmly together.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
77 words
A thermo-plastic fabric capable of being shaped or wrought into rigid form, directly by the action of heat, comprising: a first woven fabric formed predominantly of fibers of thermoplastic material for forming a thermoplastic matrix; a second woven fabric superimposed in contacting relationship with the first woven fabric, and formed predominantly of fibers of reinforcing material for reinforcing said thermoplastic matrix once formed; joining means for joining the first and second woven fabrics together at spaced locations.
Claim 2
Dependent Claim
77 words
A thermo-plastic fabric capable of being shaped or wrought into rigid form, directly by the action of heat, comprising: a first woven fabric formed predominantly of fibers of thermoplastic material for forming a thermoplastic matrix; a second woven fabric superimposed in contacting relationship with the first woven fabric, and formed predominantly of fibers of reinforcing material for reinforcing said thermoplastic matrix once formed; joining means for joining the first and second woven fabrics together at spaced locations.
Claim 3
Dependent Claim
15 words
A fabric as in claim 1, further comprising reinforcement fibers in the first woven fabric.
Claim 4
Dependent Claim
15 words
A fabric as in claim 1, further comprising thermoplastic fibers in the second woven fabric.
Claim 5
Dependent Claim
50 words
A fabric as in claim 1, further comprising: a third woven fabric formed predominantly of thermoplastic fibers superimposed in contacting relationship with the surface of the second woven fabric opposite the first woven fabric; and means for joining the third woven fabric to the second woven fabric at spaced locations.
Claim 6
Dependent Claim
52 words
A fabric as in claim 4, wherein the thermoplastic fibers of the first woven fabric, upon melting, serve as a matrix for the reinforcement fibers of the second woven fabric; and the thermoplastic fibers of the third woven fabric, upon melting, serve as an adhesive for adhering the fabric to a surface.
Claim 7
Dependent Claim
22 words
A fabric as in claim 1, wherein the joining means comprises a binding fiber knitted into the first and second woven fabrics.
Claim 8
Dependent Claim
22 words
A fabric as in claim 1, wherein the joining means comprises a binding fiber woven into the first and second woven fabrics.
Claim 9
Dependent Claim
25 words
A fabric as in claim 1, wherein the material forming the reinforcing fibers is selected from the group consisting of glass, aramid, carbon and silica.
Claim 10
Dependent Claim
31 words
A fabric as in claim 1, wherein the material forming the thermoplastic fibers is selected from the group consisting of polyetherimides, polyetherketones, liquid crystal polymers, polyphenylene sulfides, polyether sulfides and polycarbonates.
