Pullwinded carbon fibre tubes, fibre orientation mainly longitudinal (single direction) + torsion reinforcement. Excellent tensile strength, resistance to pressure and flexural strength.
Matrix resin: Vinyl ester (more information see R&G eWiki, in german only, translator included).
Light weight, high strength, excellent corrosion and heat resistance and electrical conductivity.
Due to the manufacturing process, the surface of these tubes is not absolutely smooth. The carbon fibres of the outer torsion layers are visible and can be slightly felt.
Deviation in diameter ± 0.2 mm. Deviation in the straightness max. 2 mm / m. The measured values are generally well below the maximum.
The pipes' surface should not be grinded, as this damages the upper layers of fibre and the pipe loses its strength. However, if a pipe still needs to be ground, e. g. for bonding, then one should proceed very carefully in order to damage as few fibres as possible.
Internal release agents are used in the pultrusion process, which migrate to the parts surface. Due to this bonding surfaces have to be roughened very thoroughly.
