Polar winding or filament winding is a fabrication technique that is mainly used for manufacturing open (cylinders) or closed end structures (pressure vessels or tanks). This process involves winding filaments under tension over a rotating mandrel.
The Composite Structures (FRP) Research Centre, also known as the Fibre Reinforced Plastics (FRP) Centre was started at IIT Madras in March 1974. It was started due to the increased use of FRP, on a global scale, for advanced technology applications as well as for commercial and domestic applications. Prior to the formation of the Centre, in 1960, research and development activities in this area were initiated by the Department of Aeronautical Engineering (IIT Madras) because of the possible and increasing applications of FRP in the Aerospace field in India. In 1971, Prof. K. A. V. Pandalai was awarded the CSIR (Council of Scientific and Industrial Research) Silver Jubilee Award of 6.25 lakh rupees to set up the FRP Research Centre at IIT Madras. He was the first Director of this centre.
