Abstract
Official abstract text for this publication.
The disclosure relates generally to a method for reducing the thermal expansion/shrinkage behavior between fiber reinforced plies and monolithic matrix plies, and reducing the macroscopic defects that occur during process of making a ceramic matrix composite article.
First claim
Opening claim text (preview).
1 . A method of making a ceramic matrix composite article with reduced macroscopic defects, said method comprising: forming continuous fiber reinforced prepreg tapes; forming unreinforced matrix, tapes, wherein said unreinforced matrix tapes have chopped or milled fibers and precursors to the ceramic matrix material incorporated therein, wherein a diameter of the chopped or milled fibers is from about 1 μm to about 15 μm and a length of the chopped or milled fibers is from about 20 μm to abou…
