Abstract
A process is proposed for producing a component, in which at least one first two-dimensional laid scrim is produced from a fibre composite material having a constant thickness, an outer face and an inner face. At least one second two-dimensional laid scrim is arranged with respect to the first two-dimensional laid scrim and then consolidated. The first two-dimensional laid scrim can be provided in a continuous, efficient production process, which increases speed and lowers costs.
Claims13
A process for producing a component, comprising:
- producing an even number of first two-dimensional laid scrims from a fibre composite material having a constant thickness, an outer face, and an inner face, where each of the first laid scrims has a two-dimensional extent that determines the two-dimensional extent of the component, and wherein the even number of first laid scrims comprises an outer first laid scrim and an inner first laid scrim;
- producing at least one second two-dimensional laid scrim from the fibre composite material, where the two-dimensional extent of the second laid scrim is less than that of the first two-dimensional laid scrims;
- selectively positioning at least a portion of the at least one second laid scrim at discrete regions of the inner face of the outer first laid scrim to increase a local thickness in order to increase local strength;
- and
- positioning the inner first laid scrim such that the portion of the at least one second laid scrim is arranged between the outer first laid scrim and the inner first laid scrim, and
- consolidating the composite composed of the inner first laid scrim, the outer first laid scrim, and the second laid scrim at least under application of pressure.

A component comprising:
- an even number of first two-dimensional laid scrims comprising a fibre composite material having a constant thickness, an outer face, and an inner face, where each of the first laid scrims has a two-dimensional extent that determines the two-dimensional extent of the component, and wherein the even number of first laid scrims comprises an outer first laid scrim and an inner first laid scrim;
- and
- at least one second two-dimensional laid scrim composed of the fibre composite material, wherein the two-dimensional extent of the second laid scrim is less than that of the first two-dimensional laid scrims;
- wherein at least a portion of the second laid scrims are disposed at discrete regions of the inner face of the outer first laid scrim to increase a local thickness in order to increase local strength;
- wherein the inner first laid scrim is positioned such that the portion of the at least one second laid scrim is arranged between the outer first laid scrim and the inner first laid scrim;
- and
- wherein the composite composed of the inner first laid scrim, the outer first laid scrim, and the second laid scrim has been consolidated at least with application of pressure.
