Composite beams were aged for a year and fivesamples of composite beams were examined for vibration tests within 3 months interval. Validation of test method was done by using ANSYS. Results show that a combination of water and temperature natural aging condition has the most severe effect on composite beams %K Carbonfibre %K Environmental degradation %K Dynamic testing %K VARIM %U https://journals.sagepub.com/doi/full/10.1177/096369351802700201
