WebbIn this paper, isotropic pitch and anisotropic pitch with similar physical properties were chose to be precursors for activated carbons. Chemical activations with same conditions were carried out and the characteristic difference of activated carbons from different pitch precursors was discussed. As a result, isotropic pitch with more noncrystallite carbon … WebbThis chopped carbon fiber is utilized in compression molding processes to produce highly complex composite structure. Longer fibers (1–2 inches/25–50 mm) provide higher tensile strengths, while shorter fibers (0.5 inch/12 mm) allow for molding more complex shapes.
