Scientists from the Indian Defence Research and Development Organisation (DRDO) have recently patented a breakthrough biotechnological process that can be employed to produce kevlar aramid fibres used extensively in aircraft, space systems and rocket motor casings. These are also used as high-strength materials to make fibre-reinforced polymer matrix composites that find various applications in aircraft as well as space-related industries. DRDO's newly-patented process overcomes a major hurdle faced in all conventional modes of developing kevlar aramid fibres
