Joining of Sandwich Structure

Joining of Sandwich Structures


Lightweight, high temperature stable structures are highly demanded for aerospace and energy applications.

Sandwich structures are produced by joining two .jpg/strong Ceramic Matrix Composites (CMC) skins with a porous ceramic foam core.

It is quite challenging to produce strong sandwich structures because of few connecting points between the skin and core, especially with a high porosity (˃ 80%).

By Refractory Metal (RM)-wrap technology, we are able to join ceramic sandwich structures with excellent oxidation (1100 °C) and thermal shock (RT- 1100 °C-RT) resistance [1, 2].
