摘要

A vacuum assisted resin transfer molding method for producing a component (18, 19), in particular a spar cap, of a rotor blade (5) comprising a lightning protection system (35), wherein the vacuum assisted resin transfer molding method comprises the steps of: a) placing (S1) an electrically conductive beam fiber material (22') of an electrically conductive beam (22, 23), an electrically conductive fiber mat (33, 34) and an electrical conductor (32) of the component (18, 19) in a mold arrangement (40), b) electrically connecting (S2) the electrically conductive beam fiber material (22') to the electrical conductor (32) by means of the electrically conductive fiber mat (33, 34), wherein an electrical connection (62) between the electrical conductor (32) and the electrically conductive fiber mat (33, 34) is generated, c) subjecting (S3) the mold arrangement (40) to underpressure (61), d) applying (S4) an external pressure (64) on the electrical connection (62) from outside the mold arrangement (40), e) injecting (S5) resin (59) into the underpressurized mold arrangement (40), and f) applying heat (S6) to the mold arrangement (40) for curing the resin (59).
