ABSTRACT:
In one embodiment, an apparatus for curing a composite assembly may include a base tool, a growth control apparatus, and at least one engagement filling. The base tool may have a different thermal expansion growth rate than a composite assembly to be cured using the apparatus. The growth control apparatus may have a different thermal expansion growth rate than the base tool. The engagement fitting may be movably disposed relative to the base tool and connected to the growth control apparatus. The engagement filling may hold a composite assembly being cured against the engagement filling. The growth control apparatus may grow a pre-determined amount during curing of a composite assembly to produce a cured composite assembly having a pre-determined design dimension.
