Popis: In this work, modified phenolic resin was synthesized successfully by mixing phenol, formaldehyde, and tetraethyl orthosilicate (TEOS) under certain conditions. The synthetic phenolic resin was characterized by Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), and thermogravimetry–differential scanning calorimetry (TG-DSC). It was shown that the absorption peak for the Si-O-Si structure was located at 1097 cm−1 in modified phenolic resin. The produced SiO2 granules were uniformly dispersed throughout the polymer matrix, and the size of the granules was in the range of 2–10 μm. The results also indicated that the inorganic particles could improve the thermal stability of the polymer at high temperature. The weight loss of the phenolic resin with 3.0 wt% silicon was lower and the temperature of its exothermic peak was higher. Friction materials with different phenolic resins were investigated using friction and wear tests. Friction properties such as friction stability and ...
