3. Experimental Testing 3.1. Tensile Testing

Five specimens of each material were prepared for testing of the tensile strength of materials by using Tensile Testing. The test was conducted by following ASTM D3039. The sample thickness was around 3 mm with a width of 25 mm. Tests were performed in a universal testing machine (Shimadzu AG-100) at room temperature and the crosshead speed was 2 mm/min. Some of the test specimens and tensile testing setup can be seen in Figure 2. The elongation and force values were recorded through the experiments.

The ultimate flatwise tensile strength of the material can be calculated by the following formula: = (1) where is ultimate flatwise tensile strength in MPa, is maximum force before the failure in N, and is the cross-sectional area of specimens in mm 2 . The experimental results for each specimen can be seen in Table 2.
