<p>A method of fabricating a composite structure wherein a porous laminate (10) comprised of a plurality of plies of fibrous material (12, 14, and 16) in an uncured resin matrix has entrapped air expelled. In carrying out the method, the laminate (10) is positioned in an evacuable chamber (28). Vacuum is applied to the chamber (28) to create a partial vacuum environment therein. The laminated (10) is heated to within a temperature range wherein the resin matrix exhibits a viscosity which allows air migration through the resin matrix. The laminated (10) is maintained within a temperature range for a time duration sufficient to expel entrapped air. The laminate (10) can then be cured using vacuum to compress the laminate (10). </p> |
