Carbon as a material is almost indispensable in our modern world. After all, it has long since been introduced in everyday areas in addition to the well-known fields of application in aerospace and motorsport: be it in vehicle construction, in sports, in prostheses or orthotics, in earthquake-proof house construction or as a design object in your home.

Carbon, or rather a carbon fiber laminate, achieves in some areas characteristics that conjure a shine in the eyes of every designer.
In particular, it is about the tensile strength, which is up to nine times higher than common steel. As with other materials, it's the same: for almost every task there are special fibers and synthetic resin systems available.
Through the intelligent use of fiber reinforcements, core layers and other supporting materials as well as their targeted orientation, the desired mechanical properties can be precisely determined.

The most obvious advantage of carbon compared to wood is the resistance to atmospheric agents such as humidity, heat or cold. But lesser-known properties also offer advantages when using carbon in instrument making: A carbon fiber laminate has up to three times faster sound conduction and less damping against wood. This means that addressing a musical instrument made of carbon is much faster and easier. It also contributes to the fact that carbon has no branches and irregularities, because it is not a "grown" material. In terms of density, carbon is much heavier than wood, but much stiffer.
Even mechanically, carbon is incomparably more robust and virtually no fatigue.
In order to use all these features and to produce a full and pleasant sound, it requires much more than just a few dry material parameters.
It is not enough to copy any wooden instrument. A carbon instrument must be completely redesigned and constructed. In contrast to wood instrument construction, however, there is no tradition several hundred years old. Our experience is therefore the foundation for the construction and further development of our carbon instruments.

First, a CAD model is created on the computer based on our years of research and development work. Subsequently, the model is broken down into individual components on the computer and molds are constructed. These are then milled using the existing data records.
In the molds, the carbon fiber fabrics and scrims are inserted according to a sophisticated plan. Here it depends on the fiber direction, the quantity as well as the type of fiber. The material structure can be further refined by the use of so-called core materials or other fibers. Aramid honeycombs, rigid foams, wood veneers and a wide variety of fibers and fillers are used here.
As far as possible, we use the very material- and time-consuming vacuum infusion process for our instruments. Thus, we achieve a much higher component quality than with the more common prepreg process. This is particularly important in the instrument industry, since even the smallest air bubbles in the component negatively affect the vibration behavior.
In the following steps, the individual parts are glued together and assembled to the finished musical instrument. Finally, each instrument is tuned and played to the final inspection before delivery.
