Understanding Carbon Fibre Thermal Expansion Coefficient: Key Factors and Applications What makes carbon fibre such a remarkable material in high-performance applications? One key characteristic is its unique thermal expansion coefficient (CTE), which sets it apart from traditional materials like metals and plastics. Carbon fibre exhibits anisotropic properties, meaning its CTE varies significantly along different axes—often showing negative thermal expansion along the fibre direction while having positive expansion across it. Several critical factors influence carbon fibre’s thermal expansion behavior. The manufacturing process plays a pivotal role, as the orientation and arrangement of carbon fibres within a matrix material directly affect the composite’s overall CTE. Additionally, the type of carbon fibre—whether PAN-based […]
