MATERIALS AND PROCESSING TECHNOLOGY FOR A CFRP FUSELAGE

摘要

The project “Black Fuselage“ of the German Aerospace Center DLR will further develop the competence of the aircraft design capabilities. The main objective is the reduction of the manufacturing costs by 40% of today’s metal-constructed fuselage by 2010. With a fiber reinforced design the fuselage weight of a commercial standard body aircraft can be 5 to 8 tons less (which is about 30%). Additionally, Carbon Fiber Reinforcement Plastic (CFRP) needs less maintenance compared to common metal-alloys. Also comfort and crash security, higher fire-resistance and life expectancy will increase. The object of this presentation is the design concept of a CFRP Fuselage, the technological background, the essential steps of the production process and the experiences made during manufacture of large foam core sandwich Panels for the CFRP fuselage demonstrator manufactured in a Liquid Resin Infusion Technology.
