Pyrolysis of polyethersulfone to yield in-situ carbon: A path to enhance thermal conductivity and ablation resistance of ZrB2-SiC ceramics

Key Points

• Enhanced thermal conductivity was observed in ZrB2-SiC ceramics due to carbon produced from pyrolysis.
• The pyrolysis process of polyethersulfone significantly improves ablation resistance of the ceramics.
• Analysis of the thermal properties was conducted using in-situ methods under controlled conditions.
• This enhancement suggests potential for more durable ceramic materials in high-temperature applications.
