Abstract
A multi-dimensional (e.g., 3D braided) preform formed of reinforcement strands or filaments is rigidized by impregnating the preform with a resin solution (e.g., silicone resin solution), curing the resin to impart a selected shape to the preform and then heating the shaped preform to convert the cured resin to inorganic solids (e.g., silica solids) so dispersed in an effective amount between the strands as to rigidize the preform. The rigidized preform is then infiltrated with an inorganic matrix (e.g., a ceramic material) to form a composite article.
