Braided preform

The method involves braiding a plurality of fiber bundles, each comprising a reinforcing fiber overwrapped by a plurality of glass or metal matrix-forming fibers, to form a 3D braided preform having stuffer fiber bundles extending longitudinally therethrough and heating the preform at a temperature...

Zusammenfassung:	The method involves braiding a plurality of fiber bundles, each comprising a reinforcing fiber overwrapped by a plurality of glass or metal matrix-forming fibers, to form a 3D braided preform having stuffer fiber bundles extending longitudinally therethrough and heating the preform at a temperature and applying pressure to form the matrix-forming fibers into a bonded matrix in which the reinforcing fibers are disposed in a 3D braided pattern and in a longitudinal (stuffer) pattern.
