This article discusses observations on thermal stability, decomposition properties and degradation of organic components of friction composite materials fabricated by powder metallurgy techniques. N-Methylaniline modified phenolic resin used as a binder material in the preparation of composite materials. Thermogravimetry method was used to study the thermal properties of the samples. The experiments were performed on a TGA Q50 (TA Instrument) in an oxygen atmosphere. In order to better assess the thermal characteristics of the composites, the analyses were carried out by separating thermographs into three parts according to the degradation mechanism. The obtained results helped to assess the thermal stability of the friction materials. The degradation of phenolic resin was observed in the temperature range of 312–362°C. It was found that barite and copper-graphite particles improve the thermal characteristics of the samples.

本文讨论了对粉末冶金技术制造的摩擦复合材料的有机组分的热稳定性、分解性能和降解的观察。N-甲基苯胺改性酚醛树脂在制备复合材料中用作粘合剂材料。采用热重法研究样品的热性能。实验在氧气气氛中在 TGA Q50（TA 仪器）上进行。为了更好地评估复合材料的热特性，根据降解机制将热像图分成三部分进行分析。所得结果有助于评估摩擦材料的热稳定性。在 312-362°C 的温度范围内观察到酚醛树脂的降解。
