CARBON FIBER ADVANCEMENTS
In the early 1970s, it was discovered that heating pitch (petroleum or coal based) would produce a high carbon organic precursor that could be used to produce carbon fibers. Pitch-based carbon fibers deliver superior modulus and thermal conductivity but come up short in tensile strength and compression strength as compared to PAN-based carbon fiber.
Continuing research and development on these novel carbon fiber materials in the years that followed led to the innovations that we see today. Carbon fibers from all three precursor types are commercially available today but PAN dominates with well over 90% of carbon fibers being produced from this precursor.
