A system and method for manufacturing composite parts has been developed which offers the ability to produce composite parts in an infusion resin process without the use of expensive preforms or tools. In addition, the methods of manufacturing composite parts described herein offer the ability to produce composite parts having complex structures without the need for complex tooling. The method of manufacturing and systems described herein typically include printing a part skeleton using an additive manufacturing process followed by infusing the part skeleton with resin and curing the resin infused part skeleton to form the composite part.

Multi-planar fiber matrix tool-less preform for resin infusion

A method for forming a composite structure includes the steps of: forming a fiber-reinforced polymer paste to a shape of a cavity of a dry fiber preform structure; heating said dry fiber preform structure having said fiber-reinforced polymer in said cavity to an infusion temperature; infusing resin into said dry fiber preform structure and around said fiber-reinforced polymer; and curing said resin-infused fiber preform structure and said fiber-reinforced polymer at a cure temperature higher than said infusion temperature.

Method for forming a composite structure

A fiber preform is infused with two differing resin systems concurrently using stacked resin delivery assemblies located along one edge of the preform.
