The viscoelastic behavior of composite materials is dependent on a number of factors such as reinforcement geometry, dimensionality, and continuity. The present article examines the viscoelastic properties of epoxy resin, epoxy matrix composites reinforced with cross-plied E-glass fibers, and epoxy matrix composites filled with multiwall carbon nanotubes (MWCNTs) with respect to storage modulus, loss modulus, loss factor (tan), and glass transition temperature as examined by dynamic mechanical thermal analysis (DMTA). The findings showed that when the temperature was raised, there is increase in the storage modulus, loss modulus, and loss factor of the pure epoxy resin, cross-plied E-glass fiber-reinforced epoxy resin polymer matrix (42% fiber volume fraction), and 2% MWCNT-filled epoxy resin polymer matrix composites. In comparison to pure epoxy resin and MWCNT-filled epoxy resin polymer matrix composite, the composite incorporating cross-plied E-glass fiber epoxy resin polymer matrix composite has a higher glass transition temperature, loss modulus, storage modulus, and loss factor. This shows that the resin molecules are resisted from moving through the cross-plied glass fibers.
