Özet

In this study; a polymer composite was produced by adding different proportions of polystyrene (PS), styrene ethylene butadiene styrene
thermoplastic block copolymer (SBS) and montmorillonite nanoclay into low density polyethylene (LDPE). Six different polymer
composites were produced by mixing all materials in a twin screw extruder. Later, standard test samples were molded from the obtained
polymer composites by injection molding method. To learn about the various mechanical properties of polymer composite materials
obtained; tensile, three point bending, hardness, impact tests were conducted to obtain information about the various mechanical properties
of the composite. In addition, in order to see the distribution of nanoclay powders in the matrix, photographs of the broken surfaces obtained
from the impact tests were taken with scanning electron microscopy (SEM). According to the results of the tests, with the increase of
nanoclay powder ratio in the matrix; elasticity modulus, tensile strength, flexural modulus, maximum bending strength and hardness values
were increased but % elongation, impact strength and bending elongation values were found to decrease.
