The process is comparable to the production of reinforced concrete: But instead of a steel framework, which is cast in concrete with a mold, a carbon fiber framework is inserted into a molding tool and is sheathed in an injection molding process with a thermoplastic matrix.
Here too, the reinforcement creates an enormous increase in strength. This allows use in highly stressed components such as:
In addition the high mechanical damping of thermoplastic materials combined with the high specific stiffness (E/ρ) of the carbon-armors leads to an excellent performance in increasing natural frequency and modes (NHV (Noise Vibration and Harshness)).

Wire-shaped semifinished products are produced from unidirectional
carbon rovings and a thermoplastic matrix.
The semi-finished products are formed into 3-dimensional reinforcements by means of targeted supply and removal of heat in conjunction with conventional wire forming technology.
The plastic sheathing gives the reinforcement its stability and contributes to the reinforcement of the component.
If arranged load- appropriately even small amounts of fibers lead to a severe increase of strength and stiffness.
The robustness and the high level of automation create a high potential for savings. Plus: Subsequent reinforcement is often easily possible.
Purpose-built CAx- and FE-methods allow targeted designing and very precise property predictions of components.
