Abstract

A textile part is configured for producing a composite-material element (11) or a composite-material body (12). The textile part (10) has a reinforcing system (15) including reinforcing warp threads (16) and reinforcing weft threads (17), and a binding system (25) with binding warp threads (27) and binding weft threads (26). The reinforcing system (15) has at least one first portion (20), into which the reinforcing threads (16, 17) are interwoven with one another directly for binding to facilitate withstanding high mechanical. The reinforcing system (15) also has at least one second portion (21), in which the reinforcing threads (16, 17) form binding-free crossover locations (22) preferably laid on one another in a drawn-out state to constitute a laid structure surrounded by the binding threads (26, 27). The laid structure of the reinforcing system (15), ensures particularly good draping and deformation capability at this location of the composite material.

wherein the second portion ( 21 ) of the textile part is bordered on several sides by one or more first portions ( 20 ) of the textile part, and/or wherein the reinforcing system ( 15 ) in the second portion ( 21 ) of the textile part is enclosed between the binding weft threads ( 26 ) and the binding warp threads ( 27 ) of a binding system ( 25 ), said binding warp and weft threads being bound together at binding locations ( 35 ).

2. Textile part ( 10 ) as in claim 1 ,
wherein respectively two directly adjacent binding warp threads ( 27 ) form a stationary warp thread ( 36 b ) and a leno warp thread ( 36 a ) at the binding locations ( 35 ) in the second portion ( 21 ) of the textile part, said threads crossing each other, and wherein a binding weft thread ( 26 ) extends between the stationary warp thread ( 36 b ) and the leno warp thread ( 36 a ) at the binding location ( 35 ).

3. Textile part ( 10 ) as in claim 2 ,
wherein the stationary warp thread ( 36 b ) is formed by a reinforcing warp thread ( 17 ) or by a binding warp thread ( 27 ), and that the leno warp thread ( 26 a ) is formed by a binding warp thread ( 27 ).

4. Textile part ( 10 ) as in claim 2 ,
wherein the crossover locations between the stationary warp thread ( 36 b ) and the leno warp thread ( 36 a ) are located at the binding location ( 35 ) with the binding weft thread ( 26 ).

5. Textile part ( 10 ) as in claim 1 ,
wherein the binding warp threads ( 26 ) and the binding weft threads ( 27 ) of the binding system ( 25 ) in the first portion ( 20 ) are located on a shared side of the reinforcing system ( 15 ).

6. Textile part ( 10 ) as in claim 1 ,
wherein respectively several reinforcing warp threads ( 17 ) and several reinforcing weft threads ( 16 ) extend in the first portion ( 20 ) of the textile part and/or in the second portion ( 21 ) of the textile part.

7. Textile part ( 10 ) as in claim 1 ,
wherein the number of crossover locations ( 22 ) of the reinforcing system ( 15 ) in the second portion ( 21 ) of the textile part is the same or greater than the number of the binding locations ( 35 ) in the binding system ( 25 ).

8. Textile part ( 10 ) as in claim 1 ,
wherein the reinforcing warp threads ( 17 ) and the reinforcing weft threads ( 16 ) in the second portion ( 21 ) of the textile part are arranged in a straightened manner.

9. Textile part ( 10 ) as in claim 1 ,
wherein the reinforcing warp threads ( 17 ) and the reinforcing weft threads ( 16 ) of the reinforcing system ( 15 ) are made of a reinforcing yarn ( 18 ) and the binding weft threads ( 26 ) and the binding warp threads ( 27 ) of the binding system ( 25 ) are made of a binding yarn ( 28 ), wherein the binding yarn ( 28 ) has a cross-section that is smaller or has titer lower than that of the reinforcing yarn ( 18 ).

10. Textile part ( 10 ) as in claim 9 ,
wherein the binding yarn ( 28 ) has a core ( 29 ) and a coat ( 30 ) enclosing the core ( 29 ), wherein the core ( 29 ) has a higher melting temperature than the core ( 30 ).

11. Textile part as in claim 1 , further comprising:
a textile layer ( 13 ) comprising the textile part, and
a plastic material that is bonded to the textile layer ( 13 ).

12. Method for the production of a textile part ( 10 ) for use in the composite materials, said method comprising:
