Integrated manufacturing of REciclable multi-material COmposites for the TRANSport sector

Decomposable Double BassAACHEN, Germany -- The Institut für Textiltechnik (ITA) of RWTH Aachen University and the company mezzo-forte Streichinstrumente, Werther, Germany, jointly developed together a decomposable double bass made out of carbon reinforced plastics whose neck and corpus can be dismantled through a junction made out of carbon reinforced plastics, too.

Reduce Transportation Cost
This leads to a big advantage in terms of transport: The decomposable double bass measures 1.10 meters in the length instead of 2 meters length in disassembled condition. Thereby the decomposable double bass can be carried by car and in standard luggage boxes which saves the previous high transport costs arising when transporting by special luggage.

The actual innovation is that both the junction and the double bass are made out of carbon reinforced plastics. That is the reason why you will not miss any sound quality through a change in material between instrument and junction. Why?

• A junction has to be both rigid and robust. This makes carbon reinforced plastics an ideal construction material for building a double bass because of its high rigidity and good mechanical characteristics. 
• In case of instrument and junction made out of different materials, a phonetic inactive region within the instrument and thereby a worse sound and an unstable instrument can occur.

Furthermore, fans of instruments made out of carbon reinforced plastics are convinced that you require less energy to generate a sound on an instrument made out of carbon reinforced plastics.

The damping of carbon reinforced plastics will be lower than the damping of wood. Therefore you need less energy for a tone.
