PREPREG CARBON RODS (winding technology)

are carbon textiles pre-impregnated with resin (so-called PrePregs), which are wound around steel mandrels that are removed after curing in the oven. This manufacturing process allows materials with good structural mechanical properties and at the same time an attractive appearance (either matte or glossy).
