Area of Science:

• Materials Science
• Chemical Engineering
• Physics

Background:

• Inductive heating is crucial for high-temperature industrial processes.
• Carbon-fiber-reinforced carbon-silicon carbide (C/C-SiC) composites offer potential as susceptors due to their thermal properties.
• Understanding material structure influences heating efficiency.

Purpose of the Study:

• Investigate the behavior of C/C-SiC composites as susceptors for inductive heating.
• Determine the optimal fiber length and distribution for efficient heating.
• Correlate material structure with heating performance for digital modeling.

Main Methods:

• Experimental verification of simulation results.
• Analysis of fiber length and distribution effects on heating.

Main Results:

• Inductive heating of C/C-SiC susceptors achieves very high temperatures rapidly and efficiently.
• Complete enclosure of fibers by the silicon carbide matrix prevents oxidation.
• Material structure, including fiber length and distribution, significantly impacts heating efficiency.

Conclusions:
