Claim:
1. A method of manufacturing a composite part, the method comprising: assembling a preform in a closed cavity tool, the closed cavity tool having an upper mold and a lower mold; securing the upper mold and the lower mold between a plurality of upper adapters adjacent to the upper mold and a plurality of lower adapters adjacent to the lower mold; wherein the securing of the upper mold and the lower mold between the plurality of upper adapters and the plurality of lower adapters includes connecting the plurality of upper adapters to respective ones of the plurality of lower adapters by a plurality of rod members, such that each of the plurality of upper adapters is coupled to a respective one of the plurality of lower adapters by at least two of the plurality of rod members; providing a respective one of a plurality of springs on each of the plurality of rod members such that each, of the rod members extends through a respective one of the plurality of springs; applying pressure to the preform by compressing the plurality of springs such that each upper adapter and lower adapter transfers compressive forces generated by the plurality of springs to the upper mold and the lower mold; and curing the preform until the preform becomes a cured composite structure.
