Abstract
A method for producing a ceramic matrix composite (CMC) material includes impregnating a set of ceramic fibers with a non-fibrous ceramic material, resulting in a precursor matrix, stabilizing the precursor matrix, resulting in a stabilized matrix, and densifying the stabilized matrix using a frequency assisted sintering technology (FAST) process, resulting in a densified CMC material. The resulting densified CMC exhibits superior strength and toughness, relative to prior CMCs.
Claims20
A method for making a ceramic matrix composite, the method comprising:
- impregnating a set of ceramic fibers with a flowable pre-ceramic material, resulting in a precursor matrix;
- stabilizing the precursor matrix, resulting in a stabilized matrix;
- densifying the stabilized matrix using a frequency assisted sintering technology (FAST) process, resulting in a densified ceramic matrix composite material.
A FAST densified ceramic matrix composite material characterized by a porosity of less than 5%.
