Resumo
In recent years, carbonaceous materials have been widely studied for polymer
composite applications due to its capability to improve the engineering properties
of the polymeric matrix. Among various carbonaceous fillers, carbon nanotube,
graphene, and graphite promise to be a suitable reinforcement of polymers. Rice
husk ash (RHA), a large residue rich in carbon and silica produced by the burning
of rice husk offers also an immense potential as a carbonaceous filler for polymer
composites on account of its lowcost, lowdensity, high strength and elastic modulus,
no health risks, and renewability. This work aims at studying the effects of RHA and
graphite as fillers in polypropylene (PP) matrix composites. The composites PP/RHA
and PP/graphite were produced by melting extrusion process. The materials obtained
were subjected to mechanical tests, XRD, TG, and FEG-SEM analyses. Comparison
studies between neat PP properties and its composites were carried out.
