Please note: Internal release agents are used in the pultrusion process, which migrates to the part´s surface. A pre-treatment of the adherent due to this is necessary. These have to be roughened (abrasive paper 220 grit) and cleaned very thoroughly. Epoxy resin or cyanoacrylate (superglue) is used for the bonding itself.
The straightness of pultruded CFRP tubes is due to manufacturing reasons worse than the straightness of CFRP tubes which are manufactured with the "Pullwindig"- technology. Wound carbon tubes perform best, but are also much more expensive. Smaller diameters are straighter than large diameters. Pultruded CFRP tubes are the right choice when high strength should be achieved at a low price. The tolerances in the inner and outer diameters are low, but vary depending on the diameter typically between 0.1 mm and 0.2 mm. The tolerance of the straightness to 1 meter is in any case less than 1 mm.
