Factors Limiting the Tensile Strength of Pan-Based Carbon Fibers,

Abstract

Carbon fiber characteristics differ from those of other mat-erials in that tensile strengths do not necessarily increase with increasing moduli. The tensile strengths are also low and of a divergent nature. Likely reasons for this are that the fiber cross section is only partially crystalline, the crystal structure is not fully developed nor ideal, there are several types of flaws present, and the fiber has inter-nal stress fields. These deleterious factors may be related in an approximate equation which suggests that the most effi-cient way to improve tensile properties is to seek new fiber precursors which will provide more desirable cross sectional crystalline structures.
