Insulation Materials And C/C Composites
Chopped PAN fibres moulded and carbonised to 0.25–0.35 g cm⁻³; offers higher handling strength than needled felt while keeping thermal conductivity low.
Features
Higher compressive strength – withstands 0.3 MPa dead load at 1,600 °C
Machinable – can be turned, milled or threaded to complex insulation packs
Dimensionally stable – linear shrinkage <1 % after first fire
Rapid delivery – shorter CVI cycle than rigidised boards
Industrial Applications
Thermal Processing
Hot-face liners for vacuum hardening and brazing furnaces
Crystal-growth
Crucible-support rings for sapphire and SiC furnaces
