This work concerns the study of the mechanical properties and morphological of polypropylene hybrid nanocomposites with Brazilian smectite nanoclay the state of Paraiba (PB), at concentrations of 1, 2 and 5 % by weight nanoclay with the addition of 1 and 2 % by weight cellulose from discarded bond paper. 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.
