Abstract
A pitch composition suitable for spinning may comprise: a pitch having a softening point temperature (Tsp) of 400° C. or less, and an oxidation onset temperature (OOT) at least 10° C. below the Tsp at a ramp rate of 10° C./min. A carbon fiber may comprise: a carbon fiber produced from a pitch composition, wherein the pitch composition comprises: a pitch having a softening point temperature (Tsp) of 400° C. or less, and an oxidation onset temperature (OOT) at least 10° C. below the Tsp at a ramp rate of 10° C./min.
Claims4
A pitch composition suitable for spinning comprising:
- a pitch having a softening point temperature (Tsp) of 400° C. or less, and an oxidation onset temperature (OOT) at least 10° C. below the Tsp at a ramp rate of 10° C./min,
- wherein the pitch comprises a mesophase content of more than 5 vol %, based on the total volume of the pitch.
