Project Outline

The aim of the project is to develop a quantitative conceptual design methodology for composite pressure vessels with inherited Leak-Before-Break capability.

The concept will be based on the design of an artificial damage present in the structure, which will prevent the catastrophic failure of composite pressure vessels during their service life and enable taking preventative actions to avoid casualties and financial losses.

The development of a validated small-scale specimen approach will replace a number of experiments at vessel scale thus leading to the reduction of manufacturing times and costs in the vessels’ design phase which will be a significant industrial benefit.

Another outcome of this research will be the development of a validated robust analytical tool to support rapid investigation of the composite structure during the preliminary design process.
