Claim 0:
1. A method for mixing parts of a thermoset resin during impregnation of a composite preform, the method comprising:
loading a first storage well at a forming tool with a first part of the thermoset resin;
loading a second storage well at the forming tool with a second part of the thermoset resin;
positioning a composite preform at the forming tool;
positioning a vacuum bag atop the first storage well, the second storage well, a mixing chamber, and the composite preform;
sealing a first cover plate atop the vacuum bag over the first storage well;
sealing a mixer plate atop the vacuum bag over the mixing chamber;
flowing the first part of the thermoset resin into a mixing chamber at the forming tool via channels;
flowing the second part of the thermoset resin that is chemically distinct from the first part of the thermoset resin into the mixing chamber via the channels;
mixing the first part of the thermoset resin and the second part of the thermoset resin to form the thermoset resin within the mixing chamber; and
infusing the thermoset resin from the mixing chamber into the composite preform.
