CARBON fibre square tubes pultruded, inside round

CARBON fibre square tubes pultruded, inside round

Pultruded carbon fibre profiles made from HT carbon fibres (Torayca® T300 or equivalent) and a duroplastic matrix are drawn continuously through a die. This production method causes the fibres to be oriented unidirectionally, i.e. along the length of the pultruded form. The result is a high fibre volume fraction of 58 % with a very low air voids content.

Heat distortion temperature 120 °C

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.

As a rule, the deviation from the straightness is not more than 1 mm/m.
