ightweight composites that can withstand temperatures of up to 4000 degrees centigrade are being developed to be integrated into the new missiles to make them effective.

The main application I can think about for such a light weight composite
( note DRDO has already the technology to develop carbon carbon composite material which can withstand temperature of up to 3000* C and is being used in the nose cone of Agni class missile ) is a hypersonic vehical/missile which can travell at Mach 10-12 and perhaps a light weight ICBM .
