Pitch-Based Carbon Fibre High Modulus Properties
topic
Mesophase pitch-based carbon fibres are produced by melt spinning of liquid crystal pitch precursor, oxidative stabilisation, and high-temperature graphitisation at 2500 to 3000 degrees Celsius, yielding highly graphitised fibres with elastic modulus of 500 to 900 gigapascals, thermal conductivity of 400 to 1000 watts per metre kelvin, and negative axial coefficient of thermal expansion enabling zero-CTE composite structures.
Role
Provides ultra-high modulus and high thermal conductivity carbon fibre for space structure dimensionally stable optical benches, satellite solar array panels, and thermal management applications where pitch fibre axial thermal conductivity exceeding copper enables carbon fibre composite heat spreaders and thermal straps with aerospace-grade structural properties.
