A mortise-tenon joint inspired interface structure design for synergistically enhancing the mechanical properties and thermal shock resistance of Cf/(HfNbTaTiZr)C-SiC composites

Caption

The prepared Cf/(TiZrHfNbTa)C-SiC composites have an interface bonding mode similar to the mortise and tenon structure in ancient Chinese architecture. This bonding mode can fully exert the reinforcing effect of carbon fibers, so the composites exhibit excellent mechanical properties, thermal shock resistance and ablation resistance. Compared with other reported ultra-high temperature ceramics and composites, the obtained Cf/(TiZrHfNbTa)C-SiC composites show outstanding mechanical properties and durability in extreme environments.
