Problems solved by technology

[0010] However, the nonwoven layer is mainly responsible for the mechanical stability of the final part integrally forming a planar textile structure due to its percentage of carbon fibers, so that the presence of a reinforcing mesh has a detrimental effect on the strength-to-weight ratio of the part

Embodiment Construction

[0024] figure 1 A schematic structural design of a flat textile structure ( 1 ) according to one aspect of the invention is shown. A reinforcement mesh (3) according to the invention is fixed here between two pile layers (2) according to the invention, said reinforcement mesh (3) as represented by its mesh braces (30) , the pile layer (2) as represented by its fibers (20).

[0025] figure 2 A schematic structural design of a preferred embodiment of a flat textile structure ( 1 ) according to the invention is shown. Two vertically stacked pile layers ( 2 ) are here on one side of the reinforcement grid ( 3 ), and one pile layer ( 2 ) on the other side. This embodiment is preferred because the surface of the planar textile structure ( 1 ) exhibits better optical and tactile properties on the side with the two vertically stacked pile layers ( 2 ). This becomes advantageous mainly when only one side of the part is visible in the rear part integrally forming the planar textile...

Abstract

A flat textile structure comprising a reinforcing grid and at least one pile layer which is situated in a flat manner on at least one surface of the reinforcing grid, characterized in that the flat textile structure has a weight per unit area of from 40 to 140 g / m2, the pile layer consists predominantly of carbon fibres, the carbon fibres in the flat textile structure have a proportion of the weight per unit area of from 60 to 97%, the reinforcing grid has a proportionate weight per unit area of from 2.5 to 12.5 g / m2 and the flat textile structure is strengthened.

Description

technical field [0001] The present invention relates to a woven material that has been reinforced for improved handling during the manufacturing process, a component incorporating the reinforced nonwoven material and its use. In particular, the present invention relates to a carbon fiber nonwoven fabric having a reinforcing mesh incorporated therein. Background technique [0002] During the manufacture of planar textile structures with relatively low cohesion in the textile fibers, for example in the case of nonwovens or fleeces, the simplest handling processes cause problems, such as rolling up and unrolling said planar structures, and The planar structure is automatically supplied to further production stages. One possible way to deal with this problem is to integrate the reinforcement mesh into the planar structure. The basic structure of this reinforcing layer introduced between the pile layers represents the starting point of the invention. [0003] In DE9207367U1 a ...
