Patent ID: 6840750

Claim:
A mold assembly for distributing a resin throughout a dry fiber preform to form a composite structure, said mold assembly comprising: a first mold line tool supporting the dry fiber preform; a second mold line tool disposed on a portion of the dry fiber preform to form a hard interface between the second mold line tool and the portion of the dry fiber preform wherein the hard interface has a tight tolerance of within ±0.015 inches or less; a vacuum bag encapsulating the second mold line tool and forming an air-tight seal around the hard interface; a resin supply connected in fluid communication with the dry fiber preform and supplying resin to the hard interface; and a vacuum supply connected in fluid communication with the mold assembly, supplying vacuum pressure to the hard interface and drawing excess resin away from the hard interface such that the composite structure has a tight tolerance at the hard interface after curing.
