Abstract

In this work studies on miriti fibers (Mauritia flexuosa L.) are conducted with the purpose of examining their potential use for reinforced polymeric composites. Attributes such as diameter dimensions, shape of the cross section, microstructure and surface morphology, and mechanical properties of the fiber are investigated. Diameter average dimensions are studied from cross-section images obtained by SEM. Mechanical properties were determined by tensile tests accordance to ASTM 3379 standard on single fibers specimens. A range of results was obtained for diameter dimensions and the morphology of the cross section of fibers indicated various shapes, and images from SEM exibt the singular microstructure of miriti fiber. The tensile mechanical properties show also a variety of results, characteristic of natural fibers, but the results are similar to other natural fibers used in industry.
