HYBRID SHEET MOLDING COMPOUND TECHNOLOGIES FOR A NEW GENERATION OF CABIN AND CARGO AIRCRAFT COMPONENTS

摘要

The aviation industry is one of the branches with the highest growth during the last years.rnLightweight design and the use of lightweight materials such as carbon fiber reinforced plasticsrnare important key aspects for meeting the rising need for fuel-efficient civil aircraft in the future.rnFor the cost-efficient and lead-time-related production of aircraft structures or components therndevelopment of innovative manufacturing technologies is necessary. In this context therncombination of pre-impregnated continuous fiber reinforcements and sheet molding compoundsrnreinforced by long fibers in a one-shot compression process is really promising. By using thisrnhybrid material and this process technology functional and lightweight composite componentsrncan be realized in a cost-saving way and with short lead times. The direct implementation ofrnmetal components such as inserts, sleeves and plates promises further functional integration.rnThe current work focusses on the advancement and development of hybrid sheet moldingrncompounds with tailored and load-path-optimized continuous fiber reinforcements for cabin,rncargo and secondary structure aircraft applications. Investigations according to these hybridrnmaterials, the used process technology and the direct integration of metallic force transmissionrnelements are the key aspects of this paper.
