The flexural tests were performed according to the ASTM D-790 standard. The dimensions of the test specimens used were 74 mm in length, 13 mm in width, and 1.1 mm in thickness. The span-to-depth ratio was set to 40:1. Flexural tests were carried out using a Testometric X350-20 (UK) testing machine, which was equipped with a 20 kN load cell at a crosshead speed of 1 mm/min. At least five specimens were tested for each composite sample.
