Abstract
Novel carbon fiber in the form of a plurality of tows or bundles comprising a multitude of continuous filaments is disclosed. The novelty of the carbon fiber resides in its unique combination of mechanical properties that make it admirably suited for use in composites comprising an organic matrix. Such composites are particularly useful in aerospace applications that have designs in which weight and performance are critical.
