The Effect of Accelerated Ageing on Reaction-to-Fire Properties–Composite Materials

Abstract As material age, the durability, strength, and other mechanical properties are impacted. The lifespan of a generally decreases when exposed to weathering conditions such as wind, temperature, humidity, light. It is important have knowledge how materials age affected. Regarding materials´ fire behaviour effect ageing on these properties, limited. research questions current work are: Are composite affected by ageing? And if so, it affected? study at Technology Readiness Level 9 (TRL). In this study, three fibre laminates developed for marine applications were accelerated ageing. Two different selected, thermal with an increased temperature 90°C moisture in moderately 40°C relative humidity 90%. Samples collected after one, two four weeks reaction-to-fire was evaluated using ISO 5660–1 cone calorimeter EN 5659–2 smoke chamber FTIR gas analysis. test results showed that laminates, both phenolic/basalt composites, deteriorated from third laminate, PFA/glass composite, improved toxicity ageing, especially higher production CO HCN, aged samples.
