Paper Abstract

Theoretical intensity of carbon fibre is about 180GPa. However, the maximum intensity of carbon fibre in the available products hardly reaches 1/20 of the theoretical value. Based on micro damage principle of composites and microstructure of carbon fibre, this paper focused relationship between the actual intensity of carbon fibre and crystallization, orientation and pore conditions; searched for the analysis and calculation methods, and discussed the main factors which affected the intensity. Through novel theoretical analysis method and calculation algorithms, the theoretical obtained results were consistent with the experimental results. It is revealed that the pore density, size and orientation determine the carbon fibre intensity, which provides theoretical basis to improve the carbon fibre production.
