Composites

Composite Sonar Dome: Composite Research Centre in R&DE(E) is developing a composites sonar dome for P15 class of ships for the Indian Navy. The dome is a monocoque structure made up of E-glass reinforcement in epoxy matrix and is fabricated using Vacuum Assisted Resin Transfer Moulding. The first dome was successfully tested for acoustic performance and it is now delivered to Indian Navy for fitment on INS KolkataRealisation of the second dome is under progress.

5m Composite Bridge: The 5m composite bridge has been realised as a substitute for metallic bridges. The bridge achieves more than 40% saving in weight as compared to metallic bridges. The bridge also contains embedded fibre-optic sensors, using which structural health monitoring can be carried out.

Composite Antenna Cabin for Revathi Radar: A composite antenna Cabin for housing Revathi radar, with in-situ EMI Shielding, has been developed and realised for LRDE Bangalore, achieving about 40% saving in weight.
