Preparation and interface characterization of PF-based co-curing HXNBR damping composite
In this paper,the preparation process and interface performance characterization method of phenolic resin-based(PF)co-curing damping film composites with excellent aging resistance,high-temperature resistance and superior mechanical properties were proposed.Based on polymer synthesis theory and orthogonal experiments,the material components of hydrogenated carboxyl nitrile butadiene rubber(HXNBR)co-cured with phenolic resin matrix at 150℃ where developed,which addressed the problem of asynchronous co-curing between HXNBR and phenolic resin.The preparation process of viscoelastic material films capable of co-curing with phenolic resin was developed,and the variation rule of the interlayer bonding performance of phenolic resin-based co-curing composite materials with the HXNBR thickness was systematically studied.The occurrence of chemical reactions at the interface was confirmed by XPS and FT-IR.
