dc.description.abstract | Silica particles were produced form rice husk and used as reinforcement in
the polymer matrix. The obtained silica particles' surfaces were modified with
layered double hydroxides, which enabled better reinforcement in the PMMA matrix.
Coprecipitation was used to synthetize Fe Al layered double hydroxides (LDH) with
a Fe:Al cation content of 3:1 and an FeAl-LDH: silica ratio of 1:1. X-ray diffraction,
Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy
with EDS were used to characterize the synthesized particles. The prepared particle
amounts in the PMMA matrix were 1, 3, and 5 wt. %. The purpose of this study was
to see if the obtained SiO2 particles, as well as their modification with FeAl-LDH,
had any effect on the mechanical properties of polymer composite materials. The
mechanical characterization of obtained composites was done using Vickers
microindentation tests and impact testing. The Vickers micro-hardness test showed
that the addition of reinforcement increases the hardness of the composite. When
compared to the matrix, the toughness of the composite material with a higher
content of particles (5 wt. %) in the energy absorbed in this impact test was three
times higher. | sr |
