3.2. 3- Point Bending Tests Bending is one of the possible failure modes in composite materials and obtaining flexural properties of new types of composite materials is crucial in order to obtain application areas in future. 3-point bending tests were performed to obtain flexural properties of composite materials according to ASTM D7264. The sample thickness was around 3 mm with a width of 25 mm. The length of specimens was 200 mm for all experiments. All tests were performed in a universal testing machine (Shimadzu AG-100) at room temperature with a crosshead speed of 1 mm/min. The experimental setup can be seen in Figure 3.
