Problems solved by technology

Although the amount of epoxy resin used in FRP composite materials is much less than that of UPR, due to its unique high mechanical properties, its application in high-end composite materials still ranks first, especially in cable protection tubes. In the past, there have been many researches and progresses on epoxy resin toughening, heat resistance and meeting the new molding process. The current FRP composite material still cannot meet the demand. How to prepare a kind of toughening effect, excellent high temperature resistance and wear resistance. , good oxidation resistance and long service life FRP composite material has become a technical problem to be solved at present
