Methodology on fibre optic sensor embedding in high-pressure composite gas tank using sensor tapes in pre-fabricated fabric sheet

A simple, low-cost and robust method of integrating an optical sensor system in a composite high-pressure gas tank was developed using a pre-fabricated sheet with embedded sensors. The impact on the production process is minimal, no extra manufacturing equipment or machinery is needed.

Extensive prototype testing has been performed showing:
- 100% survivability of integration of the sensors in the composite structure of the tank,
- Very good adhesion of sensors to the composite structure
- Damage detection possible of relative small (harmless) damage

This method is especially fit for integrating a optical sensor system in filament wound structures, such as pressure vessels. The main target markets are Natural Gas and Hydrogen high-pressure tanks for the automotive and (public) transport sector.

The pre-fabricated sensor sheet adds no significant weight. The added cost to the tank is 10-20%, making it commercially feasible to use this method for manufacturing tanks with a structural monitoring system.
