Abstract
Method of manufacturing a metal matrix composite part and ceramic preform assembly for use in the method. The method includes forming a ceramic preform using 3D printing, sintering the ceramic preform to form a sintered preform, introducing a liquid metal into the sintered preform to form the metal matrix composite part. The ceramic preform may be part of a ceramic preform assembly includes at least one ceramic preform and an infiltrant reservoir connected to the ceramic preform. The method may also include forming the ceramic preform assembly using 3D printing.
Claims16
A method of manufacturing a metal matrix composite part, the method comprising:
- forming a ceramic preform using 3D printing, the ceramic preform being formed from ceramic particles, wherein forming the ceramic preform includes forming a channel in the ceramic preform;
- placing a plurality of fibers as fiber reinforcement during the 3D printing, wherein a fiber of the plurality of fibers is placed in the channel to form continuous fiber reinforcement;
- sintering the ceramic preform to form a sintered preform;
- and
- introducing a liquid metal into the sintered preform to form the metal matrix composite part.
