Carbon fibers are used instead of glass fibers as a reinforcement in the profiles for special applications. Epoxy resin as a matrix is mainly used.
The biggest difference in the properties of carbon fiber profiles (CFRP) compared to the fiberglass profiles (GRP) is the much higher stiffness (lengthwise).
The much higher price of the carbon-fiber-reinforced plastic limited the use for high-tech applications in the field of medical technology, robots, textile machinery, sports equipment, automobile and aircraft engineering, etc.
A layer, mainly based on epoxy, protects the fragile fibers from damage and facilitates subsequent processing. In addition to the great benefits of the very high (longitudinal) stiffness, it must be noted that the C-fibers have different mechanical strength properties vertical to the fiber axis, due to the structural design of the fiber.
Other physical properties like the thermal conductivity or the dilation are completely different.
In addition: the carbon fiber CFRP profiles or components are electrically conductive!
Apart from a limited standard range of (small) tubes, rods and plates are semi-finished products and components made from carbon fiber-epoxy usually available. We manufacture profiles and components with the highest precision.

The Pultruded process continuously pulls fibers from rolls, which are then wetted with a matrix material (usually a thermosetting resin like epoxy resin). Subsequently, they are pulled through a heated die, which determines the shape of the profile. Polymerisation of the resin takes place in the die, forming a rigid profile with a diameter corresponding to that of the die and a length that is endless, in theory. The extruded process guarantees an accurate design and measurement control, perfectly aligned fibres and a smooth surface. The technology is suitable for all types of fibres or a combination of fibre types. A high fibre-volume content is feasible, which makes it possible to reach a high specific rigidity and strength of the profiles. The serial character and the controllability of the process ensure a good price/quality ratio.
