Claim 14:
15. A method for infusing a preform with a thermoset resin, the method comprising:
positioning a vacuum bag atop a first storage well containing a first part of the thermoset resin, a second storage well containing a second part of the thermoset resin that is distinct from the first part of the thermoset resin, and a mixing chamber;
sealing a cover plate to the vacuum bag over the first storage well and the second storage well;
sealing a mixer plate to the vacuum bag over the mixing chamber;
applying a vacuum via the vacuum bag while a valve in the cover plate remains in a closed position in order to compact the preform;
driving the first part of the thermoset resin from the first storage well and the second part of the thermoset resin that is distinct from the first part of the thermoset resin from the second storage well towards the mixing chamber via channels;
mixing the first part of the thermoset resin and the second part of the thermoset resin together to form the thermoset resin within the mixing chamber; and
infusing a wavefront of the thermoset resin out of the mixing chamber and into the preform.
