  • Method of manufacturing a tube-and-plate structure of metal-matrix composite material
    Patent number: 6595264
    Abstract: A method of manufacturing a tube-plate structure of metal-matrix composite material in which a single mold is used having a first fiber preform of shape comparable to that of the tube, a second fiber preform of shape comparable to that of the plate, and a third fiber preform surrounding the first fiber preform where it is adjacent to the second fiber preform all placed therein. Thereafter, a metal or a metal alloy is injected into the mold along the axis of the tube via the face of the second preform that is remote from the first preform. This provides a monolithic structure that presents a high degree of thermo-mechanical stability.
