Verfahren zur Herstellung eines Verbundgebildes aus Metall und einem Kernstueck aus Zellmaterial

摘要

A method of diffusion bonding fragile metallic honeycomb-type cellular core to metallic face sheets without crushing the core and providing a controlled atmosphere sealed within the core cell spaces. At least one face sheet is initially spaced apart from the core in a furnace as a controlled atmosphere is formed in the furnace and its temperature elevated causing the spacers to yield and the face sheets to assume surface contact with the core. Compressive force applied through a yieldable media to the face sheets and the core diffusion bonds them and seals the controlled atmosphere within the core cell spaces.
