基于干法缠绕的高温环氧/国产T800碳纤维复合材料壳体性能
Properties of the high temperature epoxy/domestic T800 carbon fiber composite case based on dry winding
摘要
Abstract
Based on the characteristics of the dry winding process,a high-temperature epoxy resin system(GWE-1)suitable for the dry winding of domestic T800 carbon fiber was developed.The curing reaction kinetics,rheological behavior,storage period and mechanical properties of GWE-1 were studied.The micro-morphology characteristics of the resin fracture surface were observed.The domestic T800 carbon fiber/GWE-1 composites of ϕ150 mm and ϕ480 mm standard cases were prepared by the dry winding process,and the dry winding adaptability were verified.The internal pressure bearing capacity of the two standard cases was also tested.The results show that the epoxy system exhibits high strength and toughness,high temperature resistance,long storage time under room temperature and good winding adaptability with domestic T800 carbon fiber.The burst pressures of ϕ150 mm andϕ480 mmstandard cases are 42.9 MPaand 23.0 MPa,respectively,and the characteristic coefficients of the vessels are 55.1 km and 51.6 km,respectively.The ratio of strength transformation of domestic T800 carbon fiber is more than 90%.Therefore,the domestic T800 carbon fiber/GWE-1composites demonstrates excellent internal pressure bearing capacity and has the application potential for solid rocket motor.关键词
