Method for making ceramic matrix composites. |
摘要 |
<p>Fiber-reinforced ceramic matrix composite articles of complex shape are made with improved physical integrity and control over fiber alignment by a process wherein prepreg comprising fibers and powdered matrix is treated to shorten the average length of the fibers, then configured without binder removal into a preform of selected shape and fiber orientation, and finally consolidated with heat and pressure into a dense ceramic matrix composite article (10). Fiber breakage during the consolidation process is thereby avoided. <IMAGE></p> |
