Splet01. apr. 2016 · Both PBS and PBAT are semi-crystalline grade produced from fossil fuel based monomers. The PBS and PBAT have onset thermal degradation temperatures of 372 and 377 °C, respectively [16]. Two different lengths (2.08 ± 0.95 and 4.65 ± 2.45 mm) of miscanthus fiber were kindly supplied by New Energy Farms, Ontario, Canada. SpletMeasure the tear strength 7 times per samples, and take the average of 5 times except the highest and lowest value. Use the universal test machine for the measurement of the value. The measurement conditions shall be 100 kgf of load cell and 500 mm/min. of cross head speed. Calculate the tear strength by the below formula after the measurement.
