Method for making unitary, hollow structures

摘要

A method is disclosed for making unitary hollow structures of different kinds and shapes with a minimum of complex machining. The hollow structure is initially formed by application of open work mesh or cloth to a supporting structure such as a honeycomb structure. Material is then deposited on the mesh and within the cavity in a continuous process to build up a deposit layer lining the cavity and fully embedding the mesh to close the cavity, the deposit layer also bonding the mesh and the supporting structure. A novel fluid cooled mirror structure of unitary construction and homogeneous composition is made by the method of this invention.
