RBJ’s carbon fibre CRP unidirectional tubes are pultruded with a high volume fraction of carbon fibre in a vinyl ester or epoxy matrix.

We manufacture a wide range of unidirectional CRP tubes from 0.75mm up to 12.5mm in diameter. Unidirectional carbon fibre tubes are designed to give exceptional mechanical properties resistant to bending and torsional forces with a smooth surface finish. For carbon fibre tubes 14mm and above in diameter see our range of pull wound carbon tubes in an epoxy matrix.

Unidirectional carbon tubes are typically stocked in 5 metre lengths. We stock a range of small epoxy tubes, larger diameters & linear metres are made to order.*

As a UK manufacturer and pultrusion company we are able to tailor production and adapt to individual customer requirements. Please call us to discuss.
