CARBON fibre rod pultruded (round) (remainder)

Assortment adjustment. This discontinued item is qualitatively perfect goods without defects. Sale while stocks last.

Pultruded carbon fibre profiles made from 3K HT carbon fibres (Torayca® T300 or equivalent) and epoxy resin 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
Tensile strength: >3 GPa
Tensile modulus: >2 GPa
Density: 1.78 g/cm³
Interlaminar shear strength ILS: 100 MPa

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

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.
