Analysis on Stress Corrosion Cracking T-Type Tee Junctions for Safety Environments

Stress corrosion cracking (SCC) is a critical failure mechanism affecting various materials, particularly in environments susceptible to moisture and chemicals. This research focuses on analysing stress corrosion cracking in T-type tee junctions, comparing traditional steel components with carbon fibre-reinforced polymers (CFRPs). Although steel is a widely used material in marine engineering applications, it is prone to corrosion and degradation over time, especially without protective coatings. In contrast, CFRPs demonstrate superior corrosion resistance due to the composition of carbon fibres embedded in a polymer matrix, typically epoxy resin. This intrinsic property allows CFRPs to withstand harsh environmental conditions without rusting, thereby maintaining structural integrity. Additionally, CFRPs offer a favourable strength-to-weight ratio, providing comparable strength to steel while being significantly lighter. The implications of using CFRPs in applications prone to SCC are profound. CFRPs not only mitigate the risks associated with corrosion but also enhance the overall performance and longevity of structures. This analysis highlights the potential of CFRPs as a viable material alternative to steel in critical applications, particularly in industries where stress corrosion cracking poses significant operational challenges. The findings suggest material selection and design strategies for upgraded resilience against SCC in engineering applications.
