Research on Aging Resistance of Three Phase Composites for Anti-collision Intelligent Control of Bridge Engineering

Abstract

Abstract Aminated Carbon Nanotubes (CNTs) and Carbon Fiber (CF) materials for anticollision intelligent control of Bridge Engineering were used to enhance the properties of Bismaleimide Resin (BMI) matrix resin and then tested the moist heat aging, salt spray aging and erosion resistance in this study. The resulted show that when the aging time was 168h, after wet heat and salt spray, the flexural strength and impact strength of three-phase composites with 1.5wt% MWNTs-NH2 content can reach maximum, and the wet heat aging bending performance is 45% better than that of non-added carbon nanotubes, the impact performance is 41% higher, the salt spray aging bending performance is 43% higher and the salt spray aging impact performance is 32% higher.
