Abstract: A method of manufacturing a heat exchanger core from glass ceramic matrix composite includes placing one or more reinforcing fibers around one or more mandrels into a mold cavity. A glass matrix material infiltrates the one or more reinforcing fibers to produce an infiltrated core and the one or more mandrels is removed to create one or more passages passing through the infiltrated core.

Abstract: A method of forming a part includes forming a glass-ceramic matrix composite material to form a pre-consolidated feedstock sheet with a pre-determined shape. The pre-consolidated feedstock sheet is sectioned into a first piece of pre-consolidated feedstock sheet and a second piece of pre-consolidated feedstock sheet. The first piece of pre-consolidated feedstock sheet and a second piece of pre-consolidated feedstock sheet are assembled with a second piece of pre-consolidated feedstock sheet to form a composite layup. The first piece of pre-consolidated feedstock sheet and the second piece of pre-consolidated feedstock sheet are joined by compressing the composite layup to form a glass-ceramic matrix composite part.

Abstract: A laminate composite structure having at least one tubular region and at least one bonded region. The structure has a first composite layer, a second composite layer, a cavity, and one or more reinforcing fibers. Each composite layer comprises composite material with a top face and a bottom face opposite the top face. The top face of one is joined to the bottom face of the other along an interlaminar region. The cavity separates the bottom face and the top face to form a tube. The tube has an internal boundary defined by the bottom face and the top face. The reinforcing fibers line the internal boundary and are arranged so that the reinforcing fibers reduce the propensity of the composites layer to separate under internal pressure loading.
