“…Attalea funifera mart and leopoldinia piassaba wallace fibers have characterized and used experimentally as reinforcements of polymer matrices, finding applicability in materials that require good impact resistance and greater hardness (Sergio N Monteiro et al, 2006;Shimazaki & Colombo, 2010). Nevertheless, piassaba from Aphandra natalia has not been used experimentally in composite materials (Balcázar-Arciniega & Hernández-Olivares, 2017). This research is consistent with the promotion of the use of renewable natural resources, to reduce the detrimental effect of synthetic materials on the environment, meeting with the challenge of turn the agricultural and construction waste into useful products to improve performance and durability of cement mortar composites reinforced with vegetable fibers.…”
