Study the effect of temperature on structural, mechanical and thermal properties of PVC CaCO3 composite

الملخص EN

In the present study, the structural properties which included the X-rays diffraction, and DSC, the mechanical properties, which include tensile test, three-point bending test (Bending Test), hardness test and thermal conductivity of the polymers reinforced with calcite (PVC/CaCO3) at different temperature (25-40-80-120-160-200-220) °C.

The research results showed that the XC degree of X-ray diffraction decreased at high temperatures (220 ˚C), while the inter-polymerized polymer (PVC / CaCO3) increased at high temperatures.

The DSC test results showed that the degree of crystallinity (XC) decreases at high temperatures (220 ˚C).

The mechanical test results, their values were found to decrease at (220 ˚C) higher temperatures.

Finally, the obtained results were indicated that the thermal conductivity values decrease at (220 ˚C).
