Abstract

A mold assembly for a vacuum forming process and a method of elongating membranes of the mold assembly for the vacuum forming process. A permeable layer is disposed across a surface of a mold body such that the permeable layer overlaps a groove defined in the surface of the mold body. Membranes are disposed across the permeable layer and the mold body. A vacuum is activated to expel a gaseous fluid out of a space between the mold body and one of the membranes which creates compaction pressure during compaction that causes the membranes to elongate and transform the composite blank material into the composite preform. A pump is activated to inject a flow of fluid between the permeable layer and one of the membranes via the groove to control the compaction pressure during elongation of the membranes as the gaseous fluid is expelled out of the space.
