Dynamic Mechanical Analysis of Thermally Aged Fique Fabric-Reinforced Epoxy Composites

Dynamic mechanical analysis (DMA) is one of the most common methods employed to study a material’s viscoelastic properties. The effect of thermal aging on plain epoxy and a fique fabric-reinforced epoxy composite was investigated by comparing the mass loss, morphologies, and DMA properties of aged a...
