Abstract
A tooling assembly suitable for use in infiltrating a fibrous preform comprises a perforated fixture having a thickness. The fixture comprises a plurality of holes extending through the thickness, and a first counterbore aligned with at least one hole of the plurality of holes, the first counterbore having a first length extending partially through the thickness.
Claims16
A tooling assembly suitable for use in infiltrating a fibrous preform, the tooling assembly comprising:
- a perforated fixture having a thickness defined between a first side and an opposite second side of a monolithic body, the fixture comprising:
- a plurality of holes extending through the thickness;
- and
- a first counterbore extending partially through the thickness to define a first region in which the thickness is reduced;
- wherein a subset of the plurality of holes extends through the first region, the subset comprising at least three holes;
- and
- wherein the thickness in the first region is non-uniform, and wherein a first hole of the subset has a first length, and wherein a second hole of the subset has a second length different from the first length.
