Main Characteristics of Underexploited Amazonian Palm Fibers for Using as Potential Reinforcing Materials

This study aimed to present the morphological, chemical, structural, thermal, and tensile properties of three Amazonian palm fibers (Leopoldinia piassaba—PIASSAVA, Desmoncus polyacanthos—JACITARA, and Astrocaryum sp.—TUCUM) and their inner (INN) and outer (OUT) portions, in order to provide support for possible use of these fibers as reinforcement in composites. TUCUM and TUCUM OUT presented the narrower fibers and lower lumen diameters, while...
