Instron Universal Testing machine tensile strength measurement with

Figure 2. Tensile strength measurement with the Instron Universal Testing machine...

Strain-strength characteristics of the materials were determined in uniaxial tension mode on a universal testing machine Instron-1122 at room temperature and constant velocity of the upper beam vs = 50 mm/min. The samples present bilateral shoulder with the size of the working part of 4x20 mm. The thickness of the samples was measured with a micrometer with an accuracy of 0.01 mm. The curves load elongation was measured tensile strength a MPa and elongation at break s%. 

The dispersion of organically modified clay within polypropylene matrix was measured by XRD. The diffractogram were scanned in 20 range from 1.0 to 10° at a rate of l°/min The tensile and flexural properties were measured with an Instron 4202 universal testing machine and the notched izod impact strength was measured with an Izod impact tester, model 5102. Grafting yield of compatibilizer containing styrene was measured by IR spectroscopy, model Biorad.
