Carbon ribbon from Kapton 6H6 film was produced. The pro-perties of carbon ribbon pyrolyzed at temperatures from 900C to 1250C were improved substantially by low rates of pyrolysis and a high degree of stretch during pyrolysis. Tensile strengths to 186,000 psi and moduli to 24.3 million psi were obtained. Author, modified-PL
