โฆ Synopsis
An outline of the technological progress of PAN.based carbon fibre in the past several years is described with special emphas/s on the introduction of the newly developed high performance carbon f'dares. The tensile strength and modulus of PAN.based carbon fibres have increased significantly in recent years and consequently a wide range of usage including application for the primary structure for large commercial aircraft is now achievable with significant improvement in performance.
