Pengaruh Variasi Ukuran Partikel Marmer Statuari Terhadap Sifat Mekanik Komposit Partikel Marmer Statuari
Abstract: Manufacture a
composite material with a matrix resin epoxy
and marble statuary powder as filler is one industry-utilization of
waste. Mechanical properties of the composite material is influenced by the
particle size of the particles. variations in particle size would form
different mechanical properties. This research was conducted to investigate the
effect variations in particle size on the mechanical properties of the
composite particles. In this research variation in particle size marble statuary
used is 60 mesh, 100 mesh, 140 mesh and 200 mesh. Resin used is epoxy
resin, and composition of the volume ratio between the matrix and the particles
used in research was 80%: 20%. The method is used in the manufacture of
composite hand lay-up method. Tests performed in this research is XRD testing
on solid marble, bending strength, hardness, and SEM. XRD results obtained from
the testing phase identified in the marble statuary are Ca2O5Si , CaCO3, CaO,
SiO2 , MgO , MgCO3 , and SiC. Hardness value of composite particles of marble
is 22.3 to 48.33 HB, and flexural strength values of composite particles of
marble statuary is from 13.89 to 38.89
N/mm . Particle size is good for filler in the composite is 140 mesh particles.
Marble composite particles 140 mesh particle size has a flexural strength and
hardness highest, because SEM photograph composite of 140 mesh particle
distribution in the matrix evenly, and there is a good bond between the matrix
and particles of marble statuary.
