Composite Components

New Ways in Composites: being prototype or serial production, being Carbon, Glass, Aramid, or natural fibres, Connova Group manufactures composite components in perfection.

We realize your ideas and plans until full product maturity. Our experience, our drive for innovation and our versatility guarantees high-quality products without compromise.

We bring the extra-ordinary material properties of composites literally to carry loads.

Advantages of Composites

Fiber composite components and components have excellent properties – the engineers at Connova Group use these to realize your requirements and wishes

Strength

Not achievable with conventional materials – with comparatively low weight!

Stiffness

Adjustable stiffness in every direction – from elastic to highly rigid – allows endless application possibilities

Weight

Fiber-reinforced plastics offer unmatched lightweight potential compared to metallic solutions

Fatigue strength

Fiber composite structures fatigue much more slowly and allow a longer service life

Damping

In a dynamic environment, vibration damping is up to ten times higher than with metals

Thermal expansion

Controlled and adjustable thermal expansion up to zero expansion!

Chemical resistance

Very high resistance to many chemicals guarantees use in difficult environments

X-ray transparency

Radiation permeability allows use in medical environments with the highest requirements

Design

Fabric structure looks appealing & high-quality and offers new design options
