| Abstract Scope |
The increasing employability of natural lignocellulosic fibers (NLFs) in industrial sectors highlights the market's interest in the properties presented by these materials. NLFs have high variability in their properties, depending on factors intrinsic to the species or ecological. The present work proposes to evaluate the dimensional variation and its correlation with the variation of the specific mass of the carnauba fibers (Copernicia prunifera). The density was determined through the linear calculation by the diameter of the fibers (LCDF), together with the Archimedes Principle. The micrographs obtained by optical microscopy indicated an elliptical cross section, with an average diameter of 0.769 mm located between 0.31 to 1.21 mm. The average density by the LCDF method was not very accurate, however, according to the Archimedes principle it was 1.13 ± 0.22 g/cm3. Carnauba fibers showed characteristics equivalent to other natural fibers, highlighting the possibility of their use in composites of polymeric matrix. |
