These days various synthetic polymers are being prepared
combined with various reinforcing fillers in order
to improve the mechanical properties and obtain the
characteristics demanded in actual application. Studies
are ongoing to find ways to use lignocellulosic fibers in
place of synthetic fibers as reinforcing fillers. These
natural fillers are especially being sought since the production
of composites using natural substances as reinforcing
fillers is not only inexpensive but also able to
minimize the environmental pollution caused by the
characteristic biodegradability [5], enabling these composites
to play an important role in resolving future environmental
problems. The need for materials that are
non-toxic to the human body and have appropriate
characteristics for specific purposes is ever increasing due
to the lack of resources and increasing levels of environmental
pollution. Thus, research is proceeding to
develop composites using various recycled wastes [12,13],
especially in developing composites using most environmentally
friendly agro-wastes (lignocellulosic materials)
as reinforcing fillers and thermoplastic polymers as
matrixes. The convenience of these composites lies in the
fact that the ingredients are obtained easily from natural
wastes and hence the composites can be made relatively
easily. They can be used to resolve environmental
problems and to produce products with various physical
properties and effective functions. Lignocellulosic materials
as reinforcing fillers in plastics, in place of the previously
used inorganic substances and synthetic fibers,
offer a major benefit in terms of environmental protection.
The benefits offered by lignocellulosic materials
include making the final product light [9], decreasing the
wear of the machinery used, low cost, biodegradability
[5], and absence of residues or toxic byproducts.
