Are all of the material used to make the fuselage carbon fiber reinforced plastic and if it is, is it prepreg carbon fiber
@dlrinstituteofstructuresan6594 Ай бұрын
Yes the entire fuselage section was made of carbon fiber reinforced plastics. For all components we used LMPAEK thermoplastic material system which allows us to weld the components.

How does it do with aircraft based paints on it's surface? Or will wraps be needed? Are thermoplastics great for deflection in the wings? Or are these mainly for the fuselage in low stress areas? Will doublers and rivets fatigue the thermoplastics and have a lower barrier to NDI failures?
@dlrinstituteofstructuresan6594 4 ай бұрын
In principal thermoplastic are paintable, of course with adapted pre-treatments and paint systems, roughly comparable to thermoset composites. The structural behavior of thermoplastics is more or less equal to thermoset composites. Their major advantage is the ability for welding. With a full thermoplastic design you will get rid of fasteners. (Although crack propagation for thermoplastic is less problematic than for thermosets)

At 3:02 you see a typical aircraft/vessel structure. It could be made of aluminium, cfrp; both thermoset as thermoplast. Even you see these structure type in a ships hull, in steel. The structure shown is hence a multi-material solution. Pose the question to yourself: Did I propose the right structural solution with the production possibities in carbon thermoplastic? Or did I copy-cat a metal structure? In the EXTRA 400, the first certified composite pressure cabin in Europe, we (team of 5 of Delft University) designed a completely new structural system for that pressure cabin. It was definitly not a skin-stringer structure. IABG tested it extensively, and it was certified. DLR, be creative! Louis van Rijn, former ass. professor composite design, Delft University.

Thank you very much for your comments! The design of the upper shell was one of the specifications given in the project. On the one hand, our focus was on maturing processes that are currently still under development, and on the other hand on demonstrating these processes on a large scale and in a highly automated manner. It`s true that the use of CFR-TP`s offer new possibilities for advanced airframe concepts which should be considered within the design phase.

Former Boeing Everett where 787 is made. We use huge rotating mandrels with AFP and ATL robotic heads robotically layers of carbon-fiber epoxy resin prepreg to contoured surfaces. Reinforcing fibers are oriented in specific directions to deliver maximum strength along maximum load paths. This produces and accurate copy of inside of fuselage. Demonstrator here actually makes a more dimensional accurate product. Using an inside mold produces exact dimensions of outside surface, which is very important.

Thank you very much! The demonstrator certainly has further potential for optimization in some areas. The stacking sequence of the skin laminate was in fact specified in the project and was merely adapted to the boundary conditions of a production-orientated design. Our focus was on maturing processes undergoing technological development and demonstrating them on a large scale. This made it possible to identify technological opportunities, limits and development potential in many areas.

Thats not for an airplane but for a petrol rocket with wings, while a airplane ( an aircrfat that can plan, sail and soar by their own) can be built with flexible fabric covering with hemp fabric and a frame of recycled wood, cardboard and metal sheet And it would be 30-50% lighter compared to composite shell fabrication
@dlrinstituteofstructuresan6594 6 ай бұрын
Thank you for your comment! There are many different design concepts for manufacturing an aircraft structure. Which of these concepts ultimately finds its way into application naturally depends on various factors. A mix of materials can certainly be expedient here. We use the term "Best Eco-Mix", which intends to evaluate the build concept from production through operation to recycling. (Manufacturing and assembly processes would also be required for the use of hemp fibers and recycled wood... this is where we feel at home)

Im gesamten MFFD-barrel wurden verschiedenste Bauweisenkonzepte, Fertigungs- und Fügeverfahren abgebildet. So war es die bspw. im Projekt definiert in der Oberschale Z-Stringer und Integrale C-Spanten zu verwenden, während in der Unterschale Ω-Stringer und differentielle Spanten zum Einsatz kamen. Dies ermöglicht es einerseits die entsprechenden Fertigungs- und Fügeverfahren weiter zu entwickeln, andererseits die technologische Reife der der Prozesse und dessen Herausforderungen besser verstehen zu können.

Thank you very much for your comments! The design of the upper shell was one of the specifications given in the project. It is certainly possible to make the upper shell even lighter by optimizing the topology. In this project, however, the focus was not on optimizing the upper shell structure but rather on maturing various manufacturing and joining technologies which, among other things, should make it possible to meet the rate capability requirements in aircraft production.

Hi, thank you for your interest! Yes, actually it is carbon fibre. But the matrix, the material surrounding the fibres, is thermoplastic material, not thermoset as for the most other applications. The thermoplastic properties leads to a number of advantages, like you can weld parts together after manufacturing.

Hi everyone, I’ve add this vidéo to my favorites. Is there any update from sueden ? A car chasis out of carbon fibre is between 80 to 150kg. With 100wh per kilogram of composite will give between 8 to 15kw of battery. (If body panels added can go up to 20kw) The most efficients cars do around 8kw for 100km. So without battery a car could travel 200km per charge, (average travel per day is 40km) and with very very fast recharge supercapacitors could be the next best thing for automobile. (1kg of carbon fiber is 50kg of CO2 and 1kg of carbon make almost 2kg of composite, si even thé environnement impact of the building of the car is restrained)
