Claims12
A system comprising:
- a consumable core configured to be disposed within a hollow feature within a composite precursor, the consumable core completely enclosed by the composite precursor, the consumable core configured to be consumed during a melt infiltration manufacturing process, wherein the consumable core infiltrates the composite precursor, wherein the hollow feature is vacated by the consumable core.
A system, comprising:
- a composite precursor having a hollow feature;
- and
- a consumable core disposed within the hollow feature of the composite precursor, the consumable core completely enclosed by the composite precursor, the consumable core configured to convert into an infiltrant during a manufacturing process and infiltrate the composite precursor wherein the hollow feature is vacated during the melt infiltration manufacturing process.
