This work describes for the first time the flexural and compression mechanical behavior of Manicaria saccifera fibers–polymer matrix composites. These lignocellulosic fibers are obtained from a palm of natural occurrence at the Amazon region. Specifically here the fibrous natural mat that protects the fruits’ palm is used. The results obtained are comparable to the data from other lignocellulosic fiber–polymer matrix composites, demonstrating the feasibility of using Manicaria saccifera fibers as reinforcement. The wear behavior of the composites was also analyzed and their use as parquet floor is pointed out as a possibility.
