Abstract
This study evaluates the use of ash from two aquatic macrophytes characterized by the X-ray fluorescence technique and used as a filler in the preparation of a polymer composite. A glass plate mold was used to obtain the proposed materials. After the composites were fabricated, the specimens were cut using a laser cutting technique, and their mechanical and physical performance were evaluated for different percentages of particulate reinforcement. Our results obtained so far have shown that the inclusion of ashes on composites has not significantly altered their density. The addition of Pistia stratiotes ashes (5 %) has positively influenced its elastic modulus, with a 10 % increase when compared to composites manufactured from Resin. We also observe that composites manufactured from Pistia stratiotes have better properties than those made from Eichhornia crassipes. This might be associated with the greater metal percentages in the macrophytes composition. This proves that using Pistia stratiotes can be a viable alternative for the application.
