Abstract:
1. A reusable vacuum bag with integral fluid transfer channels for use with a base mold, the reusable vacuum bag comprising: a substantially impermeable elastomeric membrane, the elastomeric membrane having a first surface configured for positioning against a base mold and a preform positioned on the base mold, at least a portion of the first surface defining a preform-contact surface; a textured surface integrally formed on the first surface of the elastomeric membrane, the textured surface defining a fluid transfer channel; and at least one fluid extraction port in communication with the fluid transfer channel, the fluid extraction port being adapted for engagement to a vacuum pump to remove fluids from the fluid transfer channel; wherein the textured surface defining the fluid transfer channel is adapted to permit the flow of fluids between the first surface of the elastomeric membrane and a base mold surface in communication with the elastomeric membrane when the fluid extraction port is engaged to a vacuum pump.
