Thermoplastic Composites for Underwater Applications
Abstract
The composite materials used at sea are today nearly all based on thermoset resins (polyester, epoxy). However, there is an increasing number of thermoplastic matrix polymers available on the market (PP, PA, PPS, PEEK…), which offer possibilities for forming by local heating, attractive mechanical properties and the potential for end of life recycling. The reasons for the slow adoption of these materials are that they require a completely different manufacturing route compared to the current materials, they have more complex microstructure, and that there is little experience with them, particularly for thick structures. The aim of this study is to design, manufacture and test thermoplastic composite pressure vessels for 4500 meter depth, in order to establish a technical, economic and ecological assessment of the use of these materials to replace traditional composites underwater. Various material options exist but there are questions concerning the water sensitivity of less expensive thermoplastic composites (C/PA6) for these applications, more especially concerning its effect on the mechanical properties. In this study, a specific water diffusion model has been developed and semi-empirical relationships have been proposed to account for the effect of water on the mechanical properties. The effect of processing conditions have also been addressed and have shown a strong effect on the mechanical properties. Finally, thick thermoplastic cylinders were manufactured and tested until implosion. Results showed that it is possible to use C/PA6 thermoplastic composite cylinders for deep sea applications as these imploded at pressures higher than 600 bar.
