Abstract: A method of manufacturing a wind turbine blade part, such as a spar cap (41, 45), by means of resin transfer moulding, preferably vacuum assisted resin transfer moulding, where fibre reinforcement material is impregnated with liquid resin in a mould cavity, wherein the mould cavity comprises a rigid mould part having a mould surface defining a surface of the wind turbine blade part is described. The method comprises the steps of: a) stacking a plurality of fibre reinforcement layers on the rigid mould part forming a fibre reinforcement stack, b) providing at least one flow-enhancing mat (70) in the fibre reinforcement stack, c) sealing a second mould part, e.g. a vacuum bag, against the rigid mould part to form the mould cavity, d) optionally evacuating the mould cavity, e) supplying a resin to the mould cavity, and f) curing or hardening the resin in order to form the wind turbine blade part, wherein the at least one flow- enhancing mat has a longitudinal direction with a longitudinal extent between a first longitudinal end and a second longitudinal end, and a transverse direction with transverse extent between a first side and a second side. The flow-enhancing mat comprises fibre rovings (72) arranged in parallel in a warp direction, and a plurality of individual monofilaments (73) that are arranged with a mutual inter-filament distance and oriented in a weft direction.
