The reinforcements are then drawn through the wet-out tank. Pan guides function within the resin bath to keep the roving separated and to maintain tension on the strands to permit the resin to wet-out each fiber.

The resin bath can be of the standard dip tank design as in the previous picture, generally, for all roving composites, or the straight-through resin pan as in this picture for hollow sections or complex profiles. Pressure impregnation is the third method used for unique applications.
