Abstract

Renewable raw materials and recyclable thermoplastic polymers
provide attractive eco-friendly quality as well as environmental
sustainability to the resulting natural fiber reinforced composites.
We studied the possibility of using the recycled polypropylene
(PP) for production of composites based on kenaf fibers (KF) and
rice hulls (RH) as reinforcements. Polypropylene/rice-hulls (PP/
RH/CA) and polypropylene/kenaf (PP/K/CA) composites with
30% fiber (filler) content and appropriate compatibilizing agent
(CA)—a maleic anhydride grafted PP (MAPP), have been prepared
by two steps procedure: melt mixing and compression molding.
Flexural strength and thermal stability of the composites with
recycled PP were similar to those with neat PP. The composites
reinforced with kenaf fibers have shown better properties than those
based on rice hulls. The flexural strength of the composite sample
with recycled PP is 51.3MPa in comparison with 51.1MPa for
the composite with neat PP. Degradation temperatures of neat
and composite with recycled PP at residual weight 90% are
344.4�C and 343.5�C, respectively. The results obtained report the
possibility of utilization of recycled PP for the production of natural
reinforcements based composites with good mechanical characteristics
for using as construction building materials in housing systems.
