Standard tensile tests were conducted on dumbbell shaped specimens using a universal testing instrument
(Shimadzu AG-1, 10kN, Japan) with a tensile mode at room temperature.
Test speed was kept at 50 mm/min, according to ISO 527-2-1993. The notched Izod impact strength was
used to evaluate the toughness of the samples.
The notched specimens were tested with an impact test machine (ZWICK5331, German, Zwick/Roell) at room temperature, according to ISO 180-2000. The average value was calculated from at least 5 test specimens.
