Abstract: This paper focuses on the comparison of the effects of three kinds of tougheners, namely, silicic acid (TEOS), polyvinyl butyral (PVB) and nitrile rubber (NBR), on the tensile properties, impact toughness, bending properties and other mechanical properties of phenolic resin matrix composites. Based on the actual needs of evacuation platform products, the effects of tougheners on the thermal value of composites are investigated. Finally, the possible toughening mechanisms of each toughener are analyzed. The results show that the three kinds of toughening agents have significant toughening effects on phenolic resin matrix composites, and their toughening effects are related to the amount of addition and their toughening mechanisms are different.
