Process Technology for Continuous Preparation of Carbon Fiber (NAL-CF1)

Characterized by high tensile strength, high stiffness, fatigue resistance and light weight, carbon fibers are the preferred reinforcement material in the advanced composites in aerospace and other high performance structural applications.

Salient Technical Features: 

Fully Integrated Technology

(Acrylonitrile  --> PAN copolymer --> Special acrylic fiber --> Carbon fiber)

• Polymer production at 35 kg/h rate
• Precursor fiber spinning at 5 TPA
• Conversion of Precursor fiber to Carbon fibers at 5 TPA

• Carbon fiber composites in aircraft structures such as wings, rudder, elevator, aileron, flaps etc. in SARAS and TEJAS
• As composites in heat shields in Re-entry vehicle structures. 

Scale of Development:

• Pilot plant scale employing continuous processes at rates suitable for  development/ small scale production.
• Standard modulus grade carbon fibers NAL-CF1 is certified by CEMILAC for aerospace application. 

• The cost of production is sensitive to production capacity. For strategic
  and defense 300 tons per year will be quite viable.
• For general industrial applications, a capacity of 1000 to 1200 tons per year will be commercially viable.
