Abstract

The manufacturing method comprises at least one processing step for a carbon-carbon composite part ( 100, 200 ). In a first variant, the method comprises steps for machining and a step for processing the part. In a second variant, the method comprises a crushing step for the part before the processing step and a moulding step after the processing step. Application to manufacturing timepiece components ( 170, 270 ).

Claims (10)

1. A method for manufacturing a timepiece comprising:

a first machining step of machining a face of a component of the timepiece so as to create areas having a predetermined raised section;

and, following the first machining step, a processing step of processing the component of the timepiece in a carbon-carbon composite material, said processing step including performing a resining operation on the component followed by machining of the component.

2. A method according to claim 1 , wherein said first machining step further comprises creating areas having a predetermined hollow section.

3. A method according to claim 1 wherein the processing step is followed by a second machining step applied to said face of the component.

4. A method according to claim 3 further comprising at least one additional machining step, subsequent to the second machining step.

5. A method according to claim 1 wherein the processing step further comprises a vacuum-process operation and a curing operation simultaneous with the vacuum-process operation.

6. A method according to claim 5 , wherein the processing step further comprises a post-curing operation that follows the simultaneous vacuum process and curing operations.

7. A method according to claim 1 wherein said carbon-carbon composite material stems from a brake pad or disk of a racing vehicle, an airplane brake disk or a space shuttle tile.

8. A method according to claim 7 , wherein said carbon-carbon composite material is from a used part.
