PENGARUH FILLER ORAGANO-CLAY TERHADAP SIFAT MEKANIK MATERIAL NANOCOMPOSIT BERMATRIX EPOXY
Abstract
The aim of this research was to study the influence of the organoclay contents to the mechanical
properties of nanocomposites materials. In situ polymerization used to synthesize nanocomposites
epoxy-organo clay materials. Tensile test and compressive test were conducted based on ASTM
standards. The nanocomposite properties were compared to epoxy matrix polymer. The amount of
organoclay contained influence to mechanical properties of nanocomposite materials. The addition of
10.5 wt.% organoclay improved the tensile modulus about 185%. These decreases in the strength may
be attributed to the fact that agglomerates and voids were formed. The compression test result showed
that the addition of 3 .1 wt.% organoclay demonstrated a I 02% increase in compression strength and a
93% increase in load maximum compare to epoxy resin. An addition of 7.3 wt. % organoclay
demonstrated an increase of modulus of the epoxy resin by 93%. Meanwhile, the addition of 10.5 wt.
% organoclay caused the decreasing in yield compression up to 31 %.
