The application of orthogonal design, fuzzy comprehensive evaluation method, golden section method, gray correlation analysis and artificial neural network to the design and optimization of friction materials were induced. The future research trend of brake pad friction material was further explored, it was pointed out that the coupling mechanism between the components of the friction material and the influence on the performance was the hotspot in the future. The integration of the various optimization methods will be beneficial to the development and application of the new friction material.
