This chapter discusses three kinds of composites with natural
rubber (NR) and cellulose. The properties and features of several kinds of
short fibers used as fillers of NR are discussed. The chapter also discusses
the preparation and importance of nanocomposites with cellulose and
presents a review of NR/regenerated cellulose nanocomposites. NR/cellulose
composites find technological interest in that they exhibit additional features
like biodegradability and renewability, along with the inherent stiffness, low
cost and low density.
