Study of the effect of acetone dilution percentage on mechanical properties of epoxy-acetone system

الملخص EN

A series of epoxy-acetone blends have been prepared with different acetone percentages.

After stiffening, the prepared epoxy samples are cured in 40°C for 24 hrs.

Then a tensile test for the material specimens was performed by a universal computer aided testing machine. The measured tensile tests for the specimens reveal that as the acetone percentage is increased, the elastic properties are increased.

Nevertheless, when the acetone percentage reaches a maximum value, the tensile properties decreases with further increase in acetone percentages. The results are explained in terms of that the acetone additions reduces the cross linking density and reduce the brittle character of the prepared epoxy.

When the acetone content is more than (5 %), the strength becomes to decrease due to severe reduction of cross linking density.
