Figure 19: Optimization of dispersion parameters for the layers.

Figure 20: Three-dimensional optimization results. According to the graph, the model with the highest fracture energy is given input settings where the first layer is 0° and the second layer is 45°. As a result, the best layer is selected by the software as in Tab. 10: Number Layer 1 Layer 2 Layer 3 Layer 4 Max Desirability 1 0.00 45.00 90.00 -45.00 1.000 2 0.00 -45.00 45.00 90.00 1.000 Table 10: The Best layer evaluation by RSM Method.
