Özet
The efects of nanoclay (NC) addition on the thermal and mechanical properties
of glass fber-reinforced epoxy composites were investigated experimentally in
this study. Nanocomposite plates were produced for this purpose using three
diferent NC ratios (0.5%, 1%, and 1.5% by weight). Thermal characteristics of
nanocomposites were investigated using dynamic mechanical analysis, diferential scanning calorimetry, and thermogravimetric analysis. The mechanical
and thermal results obtained from composites with three diferent NC ratios
were compared with the results obtained from pure composites. The structures
of nanocomposites were investigated with the help of SEM–EDS analyses. Furthermore, the efect of nanoclay on the failure behavior of composites was also
investigated. In this study, the highest values in all mechanical properties were
obtained from samples with a 1% NC-added. Obtained from 1% NC-added samples: tensile, compressive, shear strengths, elasticity modulus, shear modulus,
and Poisson’s ratio values were 31.06%, 4.25%, 14.30%, 7.35%, 11.94%, and 12.5%
higher, respectively, than the values obtained from pure samples. Maximum loss
modulus and maximum storage modulus were obtained from samples with 1.5%
and 0.5% NC-added, respectively. In samples with 1.5% NC-added, the highest
Tan δ value was obtained. Glass transition temperatures increased with the added
NC. It was observed that the fber–matrix interfaces were more clearly separated
in the samples with 1.5% NC-added.
