Resumo
There is a global trend in seeking plant fibers to replace the synthetic fibers to obtain reinforced composites aimed at the use of renewable resources. In this context, this paper aims to develop the process of preparing maize leaf fibers, characterizing them and adapting them for applications in the construction industry and develop a reinforced polymer composite with these fibers. Corn leaves were dried in environmental tempera-ture, treated by mercerizing, then neutralized with acid solution and ashed in running water. The characteri-zation of the corn leaf fibers was carried out by X-ray diffraction, X-ray fluorescence, scanning electron mi-croscopy, specific surface area, thermogravimetry and specific mass. The mercerizing treatment was effec-tive, because the maize fibers have characteristics similar to synthetic fibers, leading to a possibility of new technological uses. The polymeric composite material was developed by extrusion processes and injection and tested for tensile testing, differential scanning calorimetry and scanning electron microscopy, thus reused an organic waste that would be disposed of by inserting it in a technological process, contributing to the re-search and development of new polymeric materials as well as to reduce waste discarded as scrap.
