METHOD FOR FORMING A COMPOSITE STRUCTURE

A method (400) for forming a composite structure includes the steps of: forming a fiber-reinforced polymer paste (310,350) to a shape of a cavity (309) of a dry fiber preform structure; heating said dry fiber preform structure having said fiber-reinforced polymer paste (310,350) in said cavity (309)...

Zusammenfassung:	A method (400) for forming a composite structure includes the steps of: forming a fiber-reinforced polymer paste (310,350) to a shape of a cavity (309) of a dry fiber preform structure; heating said dry fiber preform structure having said fiber-reinforced polymer paste (310,350) in said cavity (309) to an infusion temperature; infusing resin into said dry fiber preform structure and around said fiber-reinforced polymer paste (310,350); and curing said resin-infused fiber preform structure and said fiber-reinforced polymer paste (310,350) at a cure temperature higher than said infusion temperature.
