Abstract
Combining kenaf fiber with various eco-friendly polymer matrices provides a strategy for
producing wide range of composites that take advantage of the properties of both type of
materials, allowing design of final products in accordance to the end-use requirements
within a framework of cost, availability, recyclability, energy use, and environmental
considerations. Variety of polymers and resins which are derived from renewable raw
materials, are readily available from commercial sources.
In this paper the research was focused on development of a lightweight, environmentally
friendly, cost-effective composite materials based on kenaf fibers and biodegradable
polymer matrix derived from renewable resources.
Composite performs consisting of different amount of kenaf fiber as reinforcement and
polylactic acid (PLA) in a fiber form, were fabricated as nonwovens (produced by KEFI,
Italy Fig.1). The possibility of using conventional manufacturing process is an important
factor for industrial fabrication of composites based on renewable materials. Our
investigation has shown that kenaf fiber/PLA performs can be processed in a way similar
to polypropylene-based composites without any difficulties. Consolidation of these
composite performs was performed by compression molding, at temperature of 180oC.
Mechanical properties were characterized by bending and tensile test, as well by DMTA
and other techniques. The results have shown that high fiber/low matrix composites can
fulfill the end user requirements for partitioning boards in offices and dwelling houses.
Recycling ability of the produced kenaf fiber/PLA composites was also investigated.
