A resin-infusion system for manufacture of a composite part includes an inflatable rigid bladder defining at least one infusion-flow medium and a preform lay-up formed on the bladder such that the infusion-flow medium defines space between the bladder and preform lay-up. The system also includes a mold into which the bladder and preform lay-up are placed such that the preform lay-up is constrained against the mold a resin injection system configured to feed resin into and to flow along the infusion-flow medium and then be infused into the preform lay-up. The bladder is configured to expand against the infused preform lay-up during curing such that the infusion-flow medium is smoothed resulting in a smooth surface of the finished part. |
