Abstract

A fiber composite component having a first and a second fiber composite element each bent along a transverse axis opf the fiber composite component to have, respectively, in succession, a first and second base flange, a first and second web section, a first and second top flange and a first and second stiffening web. Respectively, the first and second base flanges are parallel to the first and second top flanges, the first and second web sections are angled with respect to each of the first and second base flanges and the first and second top flanges, the first and second stiffening webs are at right angles with respect to the first and second top flanges, and the first stiffening web and the second stiffening web are congruent with respect to one another, and are connected to one another, along a longitudinal axis of the fiber composite component.

Claims15

Dependent claims

A fiber composite component, comprising:

a first fiber composite element which is bent along a transverse axis of the fiber composite component so as to have, in succession, a first base flange, a first web section, a first top flange and a first stiffening web;
and
a second fiber composite element which is bent along the transverse axis so as to have, in succession, a second base flange, a second web section, a second top flange and a second stiffening web;
wherein the first base flange and the first top flange are arranged parallel to one another,
the first web section is arranged so as to be angled with respect to each of the first base flange and the first top flange,
the first stiffening web is arranged at right angles with respect to the first top flange,
the second base flange and the second top flange are arranged parallel to one another,
the second web section is arranged at an angle with respect to each of the second base flange and the second top flange,
the second stiffening web is arranged at right angles with respect to the second top flange, and
the first stiffening web and the second stiffening web are arranged congruently with respect to one another, and are connected to one another, along a longitudinal axis of the fiber composite component.

A method for producing a fiber composite component, wherein the method comprises the following steps:

shaping a first fiber composite semifinished part such that it has, in succession along a first transverse axis, a first base flange, a first web section, a first top flange and a first stiffening web, wherein the first base flange and the first top flange are arranged parallel to one another, the first web section is arranged so as to be angled with respect to each of the first base flange and the first top flange, and the first stiffening web is arranged at right angles with respect to the first top flange;
shaping a second fiber composite semifinished part such that it has, in succession along a second transverse axis, a second base flange, a second web section, a second top flange and a second stiffening web, wherein the second base flange and the second top flange are arranged parallel to one another, the second web section is arranged so as to be angled with respect to each of the second base flange and the second top flange, and the second stiffening web is arranged at right angles with respect to the second top flange;
arranging and fixing the first fiber composite semifinished part and the second fiber composite semifinished part such that the first stiffening web and the second stiffening web are arranged congruently with respect to one another along a common longitudinal axis;
introducing a matrix material into the first fiber composite semifinished part and into the second fiber composite semifinished part;
and
curing the matrix material.
