Abstract: Methods for forming composite components with sealed bi-material interfaces include applying a sacrificial material to a surface of a substrate, over-molding the substrate and the sacrificial material with an over-molding material such that the over-molding material covers at least a portion of the sacrificial material and at least one surface of the substrate, removing the sacrificial material by deflagration to form a composite component with a channel between the substrate and the over-molding material, introducing an uncured sealant into the channel, and curing the sealant to form a sealed composite component. The method can further include removing a portion of the sealant prior to the sealant fully curing. The sealed composite component can include a passage, encircled by the channel, extending between the substrate and the over-molding material.
