Abstract
The present invention is a method of making fiber reinforced composite articles using match molds to compact a partially hollow fiber/matrix lay-up. The method comprises wrapping the matrix and fiber reinforcement about a mandrel, removing the mandrel from the lay-up or chilling the wrapped mandrel allowing for easy removal of the mandrel resulting in a relatively stiff hollow lay-up. The lay-up is then placed in a mold and compacted and cured to form the desired composite article. Such a method provides an easy method to form such complex composite article shapes as I-beam, C-beam, etc.
