INFLUENCE OF NATURAL WEATHERING CONDITIONS ON THE NATURAL FREQUENCY CHANGE OF WOVEN CARBONFIBRE REINFORCED COMPOSITES

Abstract

This paper reports the effect of three different aging natural conditions on natural frequencies of woven carbon fibre reinforced epoxy composites. 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.
