Manufacturing process

The tank construction is as follows:

  • Shell: The Shell is produced by Filament Winding process.
  • Tank ribs: The tanks construction shall include stiffener ribs to provide sufficient stiffness and rigidity to the tank.
  • End caps: The end caps are fabricated by hand lay-up application.
  • Assembly: The shell and end caps are then joined together by alternate layers of CSM and woven roving impregnated with resin.
