The static tensile tests were carried out in accordance with EN ISO 527 using the universal tensile testing machine (Instron 5966) with a 10 kN head. Measurements were performed at 25 °C at the stretching rate of 100 mm/min. The characteristic strength parameters including ultimate tensile strength (UTS), Young's modulus (E) and strain at break (εB) were determined for each material using the Bluehill 3 software. The results obtained are the average values of approximately 10 measurements.
