SUCCESS IN BUILDING A BETTER FIBER FROM CARBON REQUIRES A WORKING KNOWLEDGE OF THE COMPLEX AND OFTEN MISUNDERSTOOD TRANSFORMATIONS INVOLVED IN THE CONVERSION OF POLYMERIC PRECURSORS INTO FILAMENTARY CARBON. EACH STEP OF THE TRANSFORMATION PROCESS MUST BE CAREFULLY CONTROLLED AND OPTIMIZED DEPENDING ON THE TYPE OF PRECURSOR, IF THE STRUCTURAL PROPERTIES OF THE RESULTANT FIBER ARE TO BE CONTROLLED AND IMPROVED. CARBON FIBER IS A PRODUCT BY PROCESS. EACH PROCESSING STEP BUILDS UPON THE PREVIOUS ONE. THE PROCESS CONTROLS THE MAJORITY OF THE CHEMICAL AND PHYSICAL REARRANGEMENTS OF CARBON WHICH ULTIMATELY DETERMINE THE PHYSICAL PROPERTIES AND BEHAVIOR OF THIS UNIQUE ELEMENT. THE KEY STRUCTURAL PARAMETERS WHICH ARE IMPORTANT IN TRANSFORMING PAN AND MESOPHASE PITCH PRECURSORS INTO CARBON FIBER ARE DISCUSSED IN THIS PAPER. THE DIVERSE RANGE OF CARBON FIBER PROPERTIES WHICH ARE ACHIEVABLE BY
