Abstract: A method of making carbon fiber material according to various embodiments of the present disclosure includes forming a polymer resin to have a polydispersity index (PDI) that is less than approximately 2.5. The method further includes spinning the polymer resin to create an acrylic fiber having an acrylic fiber length. The method further includes oxidizing the acrylic fiber while stretching the acrylic fiber to create an oxidized fiber that has an oxidized fiber length that is at least one of greater than or equal to approximately 100 percent (100%) of the acrylic fiber length. The method further includes carbonizing the oxidized fiber to create a carbon fiber.
