Process for impregnating fiber rovings with highly reactive resins in the winding process

摘要

Method for the impregnation of fiber rovings (1) in the winding process, characterized in that a premixed resin-hardener mixture (9) through a mixing nozzle (7) of the metering device (2) directly onto the at the metering device (2) via a metering device (2) passed fiber roving (1) is applied, the resin-hardener mixture (9) is mixed in the mixing nozzle (7) of the metering device (2) immediately before application to the fiber roving (1) and the fiber roving (1) before the application of the resin -Hardener mixture (9) passed through at least one spreader (6) and its thickness d is reduced by 20-60% and its width b is increased by 20-60%, so that one of the dosing device (2) facing surface of the Fiber rovings (1) is enlarged and a thickness d to be penetrated by the resin-hardener mixture (9) is reduced.
