Abstract
An impregnation section of a die and a method for impregnating at least one fiber roving with a polymer resin are disclosed. The impregnation section includes an impregnation zone configured to impregnate the roving with the resin. The impregnation zone includes a plurality of contact surfaces, at least one of the plurality of contact surfaces defining a cut-away portion downstream in a run direction of the roving of a point-of-contact for the at least one of the plurality of contact surfaces. The at least one of the plurality of contact surfaces further includes an edge defined by the cut-away portion. Excess material build up is reduced by the cut-away portion.
Claims11
An impregnation section of a die for impregnating at least one fiber roving with a polymer resin, the impregnation section comprising:
- an impregnation zone configured to impregnate the roving with the resin, the impregnation zone comprising a plurality of contact surfaces, at least one of the plurality of contact surfaces defining a cut-away portion downstream in a run direction of the roving of a point-of-contact for the at least one of the plurality of contact surfaces, the at least one of the plurality of contact surfaces further comprising an edge and a face defined by the cut-away portion, the face having a linear cross-sectional profile that is oriented perpendicular to the run direction of the roving,
- wherein excess material build up is reduced by the cut-away portion.
