Abstract
Devices, systems, and methods of improving manufacture of a composite wind turbine blade are provided to reduce cure time, and minimize consumable waste. After layup of a plurality of fiber panels along a blade mold, a pre-kitted vacuum bag can unrolled and overlaid on top of the fabric panels. The vacuum bag includes a plurality of fluid channels within the bag which have a pre-formed spring element embedded therein to allow for distribution a flowable resin to permeate the fiber panels and form a fiber-reinforced structural component, e.g. wind turbine blade.
