Abstract
Methods and apparatus are provided for forming a diffusion bonded composite structure. The composite structure includes at least one internal void or feature. Surfaces to be bonded are cleaned and prepared for bonding. The exposed joints of the composite structure where the surfaces interface are sealed. The composite structure is placed in hot isostatic process furnace. The furnace is pressurized to a low pressure below 1500 pounds per square inch that forces the surfaces to be bonded in intimate contact with one another. The composite structure is heated to promote diffusion bonding at the interface of surfaces in contact with one another.
