“…Many researchers have investigated high-strength C/C-glass ceramic or C/C-metal composites by joining ceramics or metals to C/C composites. [22][23][24] Zhao et al 22 designed a wave-like porous interface in the joint of preoxidation C/C composites and Li 2 O-Al 2 O 3 -SiO 2 glass ceramics, which increased the bonding strength of the composites by 51%. Song et al 23 investigated the brazing of a preparation of C/C-Ti6Al4V composites with graphene nanoplatelets.…”

This paper was focused on the development of a new composite for high thermal insulation applications with carbon/carbon (C/C) composites, carbon foams and an interlayer of phenolic-based carbon. The microstructure, mechanical properties, fracture mechanism and thermal insulation performance of the composite was investigated. The experiment results showed that the bonding strength of the C/C-carbon foam composite was 4.31 MPa, and that the fracture occurred and propagated near the interface of the carbon foam and the phenolic-based carbon interlayer due to the relatively weak bonding. The shear load-displacement curves were characterized by alternated linear slopes and serrated plateaus before a final failure. he experiment revealed that the thermal conductivity of the C/C-carbon foam composite was 1.55 W·m−1ċK−1 in 800℃, which was 95.8% lower than that of C/C composites, proving that the thermal insulation of the new foam composite was greatly enhanced by the carbon foam with its porous hollow microstructure.
