The increasing employability of natural lignocellulosic fibers (NLFs) in industrial sectors is notorious. The data acquired of different NLFs it is of great value for the scientific community, therefore, the present work proposes to investigate the thermal properties and chemical composition of carnauba fibers (Copernicia prunifera) through Fourier transform infrared spectrometry (FTIR), thermogravimetric analysis (TG) and differential scanning calorimetry (DSC). The FTIR spectra returned characteristic absorption bands for the constituents of the NLFs. The TG analysis showed a moisture loss of 64.4 ° C, with degradation starting at 207 ° C. The exothermic and endothermic peaks observed in DSC are consistent with the degradation range of the NLFs constituents, consistent with the loss of mass observed by the TG analysis. Carnauba fibers have similar vibrational and thermal properties to other NLFs, thus showing indications of applicability in reinforcing polymeric matrices in the production of composite materials.
