CARBON COMPOSITES

We primarily develop and manufacture components made from carbon fiber-reinforced plastics, as this material class offers significant advantages when it comes to achieving maximum performance at minimal weight.

LOAD-PATH-OPTIMIZED FIBER ARCHITECTURE

Our composites are load-path optimized. This means that we align the fibers precisely along the actual load paths of the component. As a result, material is used only where needed, structural performance is enhanced, and weight is reduced to a minimum.

Manufacturing
Tailored Fiber Placement (TFP)

Textile embroidery technology places carbon fibers in optimized patterns. Digital control ensures reproducible fiber architecture in every component.

Preforming

The fiber layups are further processed into preforms, providing the foundation for the next production step.

Consolidation

Resin Transfer Molding (RTM):
A thermoset resin matrix is injected into the fiber preforms and consolidated under pressure to form composite components.

or

Hot Compression Molding (HCM):
Thermoplastic fiber preforms are consolidated under heat and pressure to form composite components.

Technical specifications of a composite part: diameter 5.03 mm, surface quality Ra 0.8 µm, load capacity over 300 N
Step 03
Quality Inspection

Robust, strictly controlled processes ensure consistently high quality in small and large series production. Integrated tests, monitoring, and statistical analyses document production stability and reproducibility.

Step 04
Series Production

Automated, reproducible, and efficient series production from a single source. Computer-controlled fiber placement and controlled consolidation ensure consistent quality across all production volumes.

Lightweight Construction

Carbon offers high specific stiffness, meaning high stiffness relative to its weight. This enables the production of lightweight components with high structural stiffness.

Stiffness

Carbon composites offer high stiffness with low weight and minimal thermal expansion, ensuring stable dimensions and precision across varying temperatures.

Fatigue Strength

In dynamic applications, composites typically exhibit excellent fatigue strength. This can enable higher cycle rates in production machinery and longer maintenance intervals.

Benefits

Key Features of our Carbon Composites

Damping

The inherent damping properties reduce vibrations, wear, and fatigue, improving stability and protecting sensitive components in high-speed applications.

Functions & Electronics

In addition to their structural role, composites can also integrate functional elements. This enables intelligent structures with embedded components.

Chemical Resistance

Depending on the matrix system, composite components can withstand aggressive media and corrosion. The chemical resistance of composites makes them a viable alternative to stainless steel in many applications.

Benign Failure

Through the specialized processing of composites, we can achieve a gradual failure of the structure. Furthermore, the fiber architecture can contribute to a benign failure behavior and increase operational safety.

Sustainability

Thanks to load-path-optimized manufacturing, material is used only where it contributes structurally. This reduces material waste. In addition, the resulting weight reduction can lower energy consumption during transportation and operation throughout the product lifecycle.

Thermal Expansion

The low thermal expansion of carbon enables highly stable dimensional accuracy. This is particularly important in precision applications where measurement accuracy must be maintained under changing environmental conditions.

Design & Aesthetics

Bionic fiber placement enables a wide range of geometries. This design freedom allows the realization of complex carbon composite components that would not be feasible with other manufacturing technologies.

Radiotransparency

With the right fiber selection, composites can be designed to be transparent to various forms of radiation (e.g., X-rays, radio waves). This enables applications such as medical imaging devices and antenna structures.

Integral Composite Design

Composite materials enable highly integrated component designs and can significantly reduce the number of individual parts required. What would otherwise require a complex metal assembly can often be consolidated into a single composite component.
