Abstract The gradual replacement of conventional materials by composite materials becomes reality when specific properties cannot be achieved by the former. Also, the search for new composites that use natural fibers or a mixture of natural fibers with synthetic fibers as reinforcement is being carried out. Thus, a research was made on the development of two composite laminates, one based on piassava fiber fabric and the other a hybrid composite based on piassava fiber and glass-E fabrics, in order to compare the mechanical behavior of both. The laminate plates were prepared and were processed for specimen manufacture in accordance with the specifications of ASTM D3039 - Uniaxial Tensile Test, and ASTM D790 - Three-point Bending Test standards. Scanning Electron Microscopy (SEM) was also performed to analyze the mechanisms of damage of the specimens. The analysis of the results of the tested specimens show they are satisfactory, as they are very akin to the results of other materials already researched by academy.
