33 Figure 2.1 Tensile testing set-up with the tensile strain measured by a laser extensometer Thermogravimetric analysis (TGA) was performed on a SDT Q600 thermogravimetric analyzer (TA instruments). The test samples were scanned from 30 to 800°C at a heating rate of 20 °C/min under continuous nitrogen flow. The temperature corresponding to a 5% weight loss was taken as the degradation onset temperature (T

Unformatted text preview: onset ). For tensile test, dumbbell-shaped specimens were prepared with a Type IV (ASTM D638) sample cutter and tested according to ASTM D 638–91. Five replicates for each formulation were tested using an Instron 4466 (capacity 500 N) at a crosshead speed of 10 mm/min. Tensile strain were monitored by an EIR laser extensometer (model LE-05). The setup for the tensile testing is shown in Figure 2.1....
