Polypropylene with 3 % by weight polypropylene graft compatibilizer (PP-g-AM) was mixed of nanoclay/cellulose using a twin-screw extruder. The specimens were prepared by the injection process. The mechanical behavior was evaluated by strength, flexural strength and IZOD impact. In addition, clay and cellulose were characterized by X-ray diffraction (XRD), X-ray fluorescence (XRF) and scanning electron microscopy (SEM). With addition of cellulose in the polypropylene increased 8 % in strength and 21 % in IZOD impact test. By SEM was observed cellulose agglomeration in hybrid nanocomposites.9447-9454openAccesscellulosemechanical propertiesmorphologynanocompositespolypropylenereinforced materialssmectitex-ray fluorescence analysisTexto completo de eventohttps://orcid.org/0000-0002-7626-880X
