Jacob Lahijani was an Iranian-American scientist and inventor in the field of material science, polymeric materials and fluoropolymer processing employed by DuPont.[1]

Education[edit]

Upon arrival in the United States from Iran, Lahijani following transfer from University of Pennsylvania, earned his bachelor's degree in Biology and Microbiology from the University of Portland.[2] From there, he earned a master's degree in Chemical Engineering and later a Ph.D. in Polymer Physics and Chemical Engineering from Pennsylvania State University.[3][4]

Inventions[edit]

Lahijani holds the title of inventor on thirty patents, some notable being:

  • Kevlar 149, highest tenacity Kevlar used primarily for ballistic, armor, and aerospace applications;[5][6][7]
  • Balanced ultra-high modulus and high tensile strength pitch carbon fibers (balanced ultra-high Young's modulus (greater than 100 Mpsi) and high tensile strength pitch carbon fiber (greater than 500 kpsi)) used extensively in automotive and aerospace applications.;[8][9] and
  • ECCtreme ECA, is a fluoropolymer (epitaxial co-crystalline alloy) holding the highest Relative Thermal Index (RTI) of any melt processable plastic in the UL database (E54681) UL Plastics – Component Database.[10][11][12] ECCtreme ECA thermal rating has broad application from cable and wire for application in the extreme environments present in the aerospace and energy sectors.[11][13][14] The invention of ECCtreme® ECA created the first new class of perfluoropolymers in decades, High-Temperature Epitaxial Co-Crystalline (ECC) Perfluoropolymer Resins. Following the Chemours spin-off from DuPont (1802–2017), ECCtreme® ECA, as with all Teflon product lines were assigned to Chemours.
