Abstract

A method of forming a composite preform includes transforming a composite blank material into the composite preform via a two-stage process. The composite blank material is disposed between first and second membranes during a first stage. The first membrane and the second membrane are disposed across first and second mold bodies in the first stage. A vacuum is activated to expel a gaseous fluid out of a space between the first membrane and the first mold body and the second mold body to form a first radius of the composite blank material during the first stage. A third membrane is disposed at least partially over the composite blank material during a second stage. The vacuum is activated to expel a gaseous fluid out of an area between the third membrane and the first mold body to form a second radius of the composite blank material during the second stage.
