Researchers from the Royal Melbourne Institute of Technology (RMIT) and Monash University in Australia have found that moisture absorption is the most crucial factor to how carbon fiber materials degrade over time. The study, which did not directly address the case of the Titan sub, found that mixed composites with both 90-degree angle and 45-degree angles weaves performed the best at resisting the water absorption degradation. However, the study found that the temperature and humidity exposed to had little impact on this process. The findings have raised questions about the future of carbon fiber in deep-sea submersibles.
