Abstract
A method of making multipart assemblies by producing single parts from ceramic composite materials that are machined and bonded together to form the multipart assembly. The method is used to make turbine engine vanes.
Claims19
A method of fabricating a multi-part assembly comprising
- applying a ceramic precursor to at least a portion of at least one of a first part and second parts;
- converting the ceramic precursor into a ceramic to bond the at least first part to the second part.
A method of forming a turbine vane comprising:
- forming an airfoil;
- forming a first platform;
- forming a second platform;
- applying a ceramic precursor to the airfoil between the first and second platform;
- and
- converting the ceramic precursor into a ceramic to bond the airfoil between the at least first and second platforms.
3 more elements
