Abstract: With excellent heat resistance and ablative property, good mechanical properties and outstanding flame retardant properties, phenolic resin is widely used in aerospace, friction materials, fire retardant and other fields. Improving the heat resistance of phenolic resin has always been a hotspot in the industry. This article reviews the heat resistance modification methods of phenolic resin in recent years, including structural modification, nano-doping, volatile capture, and ceramicization. The structural modification method is highlighted. Finally, the problems existing in this field are summarized and their development prospects are prospected.
