Study the Effect of Temperature on Structural, Mechanical and Thermal Properties of PVC/CaCO3 Composite

Abstract

Abstract:In the present study, the structural properties which included the X-rays diffraction, and DSC, the mechanical properties, which include tensile test, threepoint bending test (Bending Test), hardness test and thermal conductivity of the polymers reinforced with calcite (PVC/CaCO 3 ) at different temperature (25-40-80-120-160-200-220) °C. The research results showed that the X C degree of X-ray diffraction decreased at high temperatures (220 ˚C), while the inter-polymerized polymer (PVC / CaCO 3 ) increased at high temperatures. The DSC test results showed that the degree of crystallinity (X C ) 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). Keywords IntroductionPolyvinyl chloride PVC is one of the most commonly used man-made polymers because of the unrivalled combination of properties that it offers. It is the ratio of economic cost to performance makes it immediately more accessible than most other materials and the diversity of ways in which it

Fabrication and characterization of bioactive composite: A pilot study

“…One of the fundamental tests for evaluating composite materials is the bending test, which is used to determine their elastic properties. 48 The bending strength and young’s modulus of the unmodified PEKK (G0) were determined to be (116.84) MPa and (2.9) GPa, respectively. The elastic modulus and flexural strength of the m-CS/PEKK composites (m-CS content ranging from 5 to 15 wt%) increased when m-CS was added to PEKK compared with those of the unmodified PEKK (Tables 2 and 3).…”
