PREPREG CARBON TUBES (winding technology)

These are carbon textiles pre-impregnated with resin (known as pre-pregs), which are wound around steel mandrels that are removed after curing in the oven.

This manufacturing process produces materials with good structural mechanical properties whilst also offering an attractive appearance (either matt or glossy).
