Composite with infusion film systems and methods

Abstract:

Described are methods and systems for a composite structure that allows for out of autoclave curing. Due to the layout of the composite structure, voids within the composite structure, formed out of autoclave, is reduced. The composite structure includes a composite laminate and one or more infusion films. The composite laminate includes a plurality of fiber tows that each include a plurality of fiber strands and a resin. The resin has a first viscosity within a first temperature range. The infusion film is disposed on a surface of the composite laminate and has a second viscosity lower than the first viscosity within the first temperature range. Methods of curing the composite structure are also described.
