The characterization of lignocellulosic fibers may require structural analysis and determination of properties such as density, tensile strength, modulus of elasticity, total deformation and thermal stability. Among structural characterization, Fourier transform infrared (FTIR) analysis is very often used to determine the active molecular functional groups in the constituents of the fiber. In fact, the motion of molecular groups can interact with the transmitted infrared radiation, causing energy absorption at specific wavelengths. In this work, epoxy matrix composites with hybrid mallow/jute fibers were produced in volumetric fractions of 30 vol%, with the objective of investigating the influence of exposure to UV radiation on the functional groups of these composites. Consequently, the FTIR spectrum provides a characteristic signature for a lignocellulosic fiber in terms of functional group activity.
