Abstract
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.
