Abstract
Globally, sustainable materials that are environmentally friendly and the path towards sustainable development are needed. Natural plant fi bre utilization in various industries has seen a surge, especially in the automotive sector. Natural fi bres such as from Sansevieria and banana pseudostem are readily available and have considerable mechanical properties that make them good candidates for reinforcement epoxy resins. The dynamic mechanical properties (DMA) of Sansevieria (Sansevieria trifasciata) and banana pseudostem (Musa sapientum) woven fi bre epoxy composites are discussed. The results show that the optimum temperature range of application of the Sansevieria and banana epoxy composites is up to 50 °C. The glass transition temperature, Tg, obtained from the curves of mechanical damping factor (tan δ) was 100 °C and 120 °C for Sansevieria and banana fi bre epoxy composites, respectively.

Summary
Sustainable materials that are environmentally friendly and the path towards sustainable development is needed. Various species of banana (Musa sapientum) pseudostem fibre and sanseviera fibre have been studied elsewhere for reinforcement of composite structures. Comparative Evaluation of Dynamic Mechanical Properties of Epoxy Composites Reinforced with Woven Fabrics from Sansevieria (Sansevieria trifasciata) Fibres and Banana (Musa sapientum) Fibres is subjected to a mechanical perturbation, the resulting stress and strains are used to characterize the viscoelastic behavior of the material over a wide temperature range using either one or more frequency sweeps. In his study of DMA of woven banana/epoxy composite Venkateshwaran et al, 2012 [24] shows that plain, twill and basket weave patterns storage modulus decreases with an increase in the temperature. For the first time, is presented the dynamical mechanical analysis of epoxy composites reinforced with woven fabrics made from Sansevieria trifasciata fibres and banana pseudostem (Musa sapientum) fibres
