Abstract
A method for producing advanced composite structures includes the assembly of a number of layers of fibrous reinforcements into a desired configuration. A vacuum is applied to the reinforcement in order to evacuate any air therefrom and to consolidate the plurality of fibrous reinforcements. Resin is introduced to the reinforcement by using a flow path therethrough having entry and exit points. The vacuum is used to transmit the resin through the reinforcement between the entry and exit points. The resin flows into the reinforcement due to the pressure differential between the evacuated reinforcement and the hydrostatic pressure on the resin as well as the capillary effect on the reinforcement.
