Modeling the dynamics behavior of flax fiber reinforced composite after water aging using a modified Huet-Sayegh viscoelastic model with fractional derivatives

Popis výsledku v původním jazyce

With the growing demand for sustainable and environmental-friendly materials, NFRP (Natural Fiber Reinforced Polymer) is increasingly used in the construction fields. FFRP (Flax Fiber Reinforced Polymer) is one of the major NFRP. Both storage modulus and damping factor of FFRP are related to frequency and temperature. Time-temperature equivalent principle is applied to obtain the material properties of a wider range of frequencies. A modified Huet-Sayegh viscoelastic model based on fractional derivative is used to predict the test data, and the fitting results show good agreement. After soaked in water, the storage modulus of FFRP is reduced and its loss factor is increased. SEM (Scanning Electron Microscope) analysis shows that water weakens the fiber/epoxy interface, therefore the dynamic properties of FFRP are influenced.
