Method for manufacturing fiber composite part utilized as upper section of A-column of body of cabriolet-vehicle, involves integrating metallic reinforcement insert in fiber composite part at load critical point

The method involves winding multiple fiber layers over single or multi-part core (10) in radial braiding process. A plastic resin is injected and cured in the core, which is removed in a partial manner. A metallic reinforcement insert (14) is integrated in a fiber composite part (12) at a load criti...

More Information
Summary:The method involves winding multiple fiber layers over single or multi-part core (10) in radial braiding process. A plastic resin is injected and cured in the core, which is removed in a partial manner. A metallic reinforcement insert (14) is integrated in a fiber composite part (12) at a load critical point (12a). The insert is held in a position by magnets (16) that are inserted in the core. Core layers are made of polyurethane foam and connected with each other in detachable manner by plug connection, before winding. Independent claims are also included for the following: (1) a device for implementing the method for manufacturing the fiber composite part (2) a fiber composite part that is manufactured using the method. Die Erfindung betrifft ein Verfahren zum Herstellen eines ein Hohlprofil aufweisenden Faserverbundteiles, bei dem über einen ein- oder mehrteiligen Kern in einem Radialflechtprozess mehrere Faserlagen gewickelt, anschließend zum Beispiel Kunstharz injiziert und ausgehärtet und gegebenenfalls der Kern wenigstens teilweise entfernt wird. Es wird vorgeschlagen, dass in das Faserverbundteil (12) an zumindest einer belastungskritischen Stelle (12a) zumindest eine bevorzugt metallische Verstärkungseinlage (14; 40) integriert wird, die entweder als verlorener Kern (40) oder als eingelegte Verstärkungseinlage (14) ausgeführt ist und zum Beispiel durch Magnetkraft positioniert wird.
