Material life extension for refurbished 2-for-1 carbon brakes via ceramic solutions

A method for refurbishing a C/C disk of a second thickness and coated with a second ceramic solution for a third life, comprising:

• machining the C/C disk of the second thickness to remove a coating of the second ceramic solution from the wear surfaces of the C/C disk of the second thickness thereby forming a C/C disk of a third thickness and wherein the third thickness is less than the second thickness;
• pairing with and mechanically attaching the C/C disk of the third thickness with another C/C disk of the third thickness thereby forming a C/C split-disk of a fourth thickness, wherein the fourth thickness is greater than the third thickness;
• coating the wear surfaces of the C/C split-disk of the fourth thickness with a third ceramic solution, thereby forming a C/C split-disk of the fourth thickness coated with the third ceramic solution;
• and
• drying the C/C split-disk of the fourth thickness coated with the third ceramic solution.

A method for refurbishing a C/C split-disk of a fourth thickness and coated with a third ceramic solution for a fourth life, comprising:

• machining the C/C split-disk of the fourth thickness to remove a coating of the third ceramic solution from the wear surfaces of the C/C split-disk of the fourth thickness thereby forming a C/C split-disk of a fifth thickness and wherein the fifth thickness is less than the fourth thickness, wherein removing the coating of the third ceramic solution from the wear surfaces of the C/C split disk of the fourth thickness further removes a portion of the C/C split-disk;
• coating the wear surfaces of the C/C split-disk of the fifth thickness with a fourth ceramic solution, thereby forming a C/C split-disk of the fifth thickness coated with the fourth ceramic solution;
• and
• drying the C/C split-disk of the fifth thickness coated with the fourth ceramic solution.
