1. A method for modifying a composite component, comprising:
positioning a barrier segment between an infiltrated segment of the composite component and a green segment to form an assembly, wherein a particle size distribution varies from the barrier segment to the green segment; and
initiating an infiltration process,
wherein the barrier segment has a barrier segment permeability that is lower than an infiltrated segment permeability of the infiltrated segment, a green segment permeability of the green segment, or both the infiltrated segment permeability and the green segment permeability.
