Abstract
A method for molding high temperature composites that transmits more uniform pressures to the surface of the composites. A compliant glass, glass-ceramic, or ceramic layer is caused to apply pressure to a composite precursor and heat is applied to the composite precursor to form a composite.
Claims9
A method for molding a high temperature composite comprising:
- (a) providing a compliant layer of softened material selected from the group consisting of glass, ceramic and mixtures thereof;
- (b) applying heat to a composite precursor;
- and
- (c) causing said layer of softened material to apply pressure substantially uniformly to said composite precursor.
