| Abstract Scope |
Fibre-Reinforced Polymer (FRP) Composites are extensively utilized in the aerospace, automobile, wind turbine, and many other industries due to their high strength-to-weight and stiffness-to weight ratios, and multi-stable features. The properties of FRP composites can exhibit significant differences during their in-service lifetime due to the surrounding environmental conditions such as temperature. This study investigated the possibility of their performance degradation with the Dynamic Mechanical Analysis (DMA) tests before long-term fatigue tests, then validated the assessment with monotonic and fatigue tests. Temperature ramp DMA test revealed that operation at high temperatures, below the glass transition temperature, may have significant effects on the strength and durability of the composite material. To validate the assumption, monotonic and fatigue tests were performed at room temperature and at elevated temperature. The results demonstrated a significant degradation in tensile strength and fatigue life at higher temperatures, supporting the results from the DMA tests. |
