Abstract
A mandrel suitable for supporting an airfoil preform includes a first piece extending along a longitudinal axis of the mandrel, and a second piece in physical contact with the first piece at first interface region and extending along the longitudinal axis of the mandrel. The first piece is formed from a first material, and the second piece is formed from a second material.
Claims16
A mandrel suitable for supporting an airfoil preform, the mandrel comprising:
- a first piece extending along a longitudinal axis of the mandrel, wherein the first piece comprises an aperture extending transverse to the longitudinal axis and disposed adjacent to a first longitudinal end of the first piece, the aperture sized to receive a hook or pin for removing the mandrel from the airfoil preform;
- a second piece in physical contact with the first piece at a first interface region, and extending along the longitudinal axis of the mandrel;
- and
- a third piece in physical contact with the first piece at a second interface region, and extending along the longitudinal axis of the mandrel;
- wherein the first piece is formed from a first material;
- and
- wherein the second piece is formed from a second material.
