Description
Die Erfindung betrifft ein Verfahren zur Herstellung von Faserverbundbauteilen durch Zusammenfügen von Lagen und/oder Matten aus faserförmigen Materialien mit jeweils unterschiedlicher Faserorientierung und Herstellung von unlösbaren Verbindungen zwischen den Lagen und/oder Matten zwecks Schaffung konstruktiv vorgegebener geometrischer Bauteilformen, mit dem bei einem kostenmäßig optimalen Materialeinsatz eine optimale Anordnung unterschiedlich gestalteter Faserverbundbestandteile für herzustellende Bauteile mit beliebigen Kompliziertheitsgraden ermöglicht wird. Das Verfahren ist gleichermaßen für beliebige Faserwerkstoffe und Matrixmaterialien anwendbar.The invention relates to a method for the production of fiber composite components by joining layers and / or mats of fibrous materials, each with different fiber orientation and production of permanent joints between the layers and / or mats in order to create structurally given geometrical component shapes, with the cost optimal material use an optimal arrangement of differently shaped fiber composite components for components to be produced with any degree of complexity is made possible. The method is equally applicable to any fiber materials and matrix materials.
