TUBES
Filament winding
This technology enables the production of tubes in a wide diameter range – from 8 mm up to 500 mm internal diameter. The process involves winding fibers onto a rotating mandrel while simultaneously impregnating them with epoxy resin.
The main advantage of this method is the ability to manufacture large-diameter and long tubes from carbon fiber or glass fiber, with nearly unlimited control over fiber orientation. For glass fiber products, resin pigmentation is available to achieve the desired color.
This technology also allows the production of tubes with hexagonal, square, or other cross-sections specified by the client. The final tube geometry is primarily determined by the shape of the mandrel.

Prepreg winding
In this manufacturing process, carbon or glass fiber fabrics or mats pre-impregnated with resin (so-called “prepregs”) are used. The prepregs are wound onto a core, which determines the internal diameter of the tube. The outer diameter depends on the number of applied layers.
Similarly to filament winding, Carbon Center offers the ability to design the mechanical performance of tubes according to their intended application. A distinctive feature of tubes manufactured using this technology is the visible fabric structure on the product surface.
| Max. tube length: | up to 2 500 mm |
| Available wall thicknesses: | 0,5 mm to 10,0 mm |
| Available internal diameters: | 3,0 mm to 90,0 mm |
Pultrusion
In the pultrusion process, tubes are manufactured using dedicated calibration dies. The fibers are impregnated with resin and subsequently cured during the pulling process.
Due to the 0° fiber orientation, these tubes offer exceptional bending stiffness.
| Max. tube length: | up to 6 000 mm |
| Available wall thicknesses: | 1,0 mm to 4,0 mmm |
| Available internal diameters: | 2,0 mm to 40,0 mm |
Pullwinding
This technology is an advanced development of pultrusion, enhanced with a cross-wound outer layer. The fibers are first pulled through forming dies, after which the external surface is wrapped with the same type of fiber, creating a braided outer layer.
This process improves bending and torsional strength. However, pullwinding offers limited fiber orientation flexibility. In the inner section of the tube, fibers are aligned in a single direction, providing bending strength. The outer braided layer may have fibers oriented at a specific angle, improving resistance to bending, torsion, and compression.
