Carbon-Carbon Composite (C/C)

Carbon fiber reinforced in a graphite matrix for hypersonic heat shields.

Core Principles & Analysis

• Reinforced carbon-carbon panels protected the Space Shuttle's nose cap and wing leading edges at re-entry temperatures near 1,650 °C.
• Unlike most structural materials, carbon-carbon retains and can even gain strength at temperatures above 2,000 °C in non-oxidizing atmospheres.
• Formula 1 brake discs are carbon-carbon and routinely operate at surface temperatures above 1,000 °C.

Specifications & Metrics

• DENSITY: 1.80 g/cm³
• YIELD STRENGTH: 300 MPa (flexural)
• HARDNESS: N/A
