Study on Properties of High Temperature Resistant Resin and Its Composites
According to the technical requirements of complex pipetune one-body processing of solid rocket motor,the viscosity,thermo-gravimetric curves,rheological properties and composites properties of TDS benzoxazine resin were studied.The viscosity of less than 0.3 Pa.s of TDS benzoxazine resin at glue injection temperature was obtained by mechanical properties test.Its process operation time was more than 6 h,the resin residual yield was 55.6%under the nitrogen atmosphere at the temperature 800℃,as well as the tensile strength,compressive strength,bending strength,and shear strength properties of the composite materials were also obtained.All these study results show that TDS benzoxazine of high temperature resistant resin can meet the technical requirements of one-body processing of complex pipetune of solid rocket motor.
