ABSTRACT:
In an apparatus and method for resin transfer molding, a mold including at least two cooperating mold sections is placed in a vacuum chamber. A reinforcing material is positioned between the mold sections, which are separated from one another during evacuation of the chamber, thus maintaining the reinforcing material in a substantially uncompressed condition, to ensure that all gasses and/or liquids are evacuated from the reinforcing material and the mold prior to resin injection. After evacuation, the mold sections are brought almost into engagement to substantially define a mold cavity, and resin is injected into the mold cavity. Prior to terminating the resin injection, the mold sections are brought into engagement, and final resin injection is performed. The injected resin is then cured in accordance with the particular type of resin injected.
