|Summary||The use of fillers with nanometric dimensions is actually intensively developed as reinforcing particles in thermoplastics, rubber and thermosets. In most of the cases, such particles are spherical, and it is known that the reinforcing effect is expected to be much higher with high aspect ratio fillers. In this work, cellulose monocristals (whiskers) with an average diameter of 15 nm and average length of 1Ám are dispersed within polyvinyl chloride matrix. The mechanical properties are analyzed in both the linear and non linear domains and compared with data from modeling. In particular, the interfacial characteristics are discussed.
