Abstract

Abstract: In order to explore the co-curing conditions of rubber and matrix resin composites at 80 ℃ in low temperature environment, the free energy of chemical reaction between nitrile butadiene rubber (NBR) and E51 epoxy resin at 353.15 K (80 ℃) is simulated and calculated, and the co-curing of NBR N41 and NBR N220S damping composites is realized through experiments. A viscoelastic damping material component with excellent performance and co-curing with carbon fiber/epoxy resin matrix prepreg at 80 ℃ is determined by orthogonal test. The viscoelastic damping material component is dissolved by tetrahydrofuran solvent, and N41 and N220S damping composite specimens are prepared by brush coating and co-curing process. The scanning electron microscope is used to analyze the micro damage morphology of the composite. The damping properties and shear properties of different adhesives are obtained by testing the damping DMA and interlaminar shear tests. The data shows that the damping interlaminar properties of the composite made of butadiene acrylic rubber with high acrylonitrile content are better, and NBR N220S is more suitable as a viscoelastic damping material.
