STUDY OF BORON MODIFIED BISPHENOL-F TYPE PHENOLIC RESIN USED AS MATRIX IN HIGH TEMPERATURE RESISTANT BRAKE
-
Abstract
In this paper,the bisphenol-F and a new kind of boron modified resin whose decomposition temperature was 438℃ were synthesized.Duc to the valence bond of boron the resin has saturated and chelate ring with oxygen and carbon,the moisture proof of resin was improved considerably.The high-temperature resistance of brake with this resin as matrix is enhanced.
