| Abstract: | Phenolic urethane resin was taken as the main study object,through detecting phenol urethane resin samples at different temperatures by DMA,the DMA curves of 0~400℃of phenol urethane resin were plotted and analyzed,a temperature range of glass transition temperature and good damping properties of phenol urea resin were found.By processing the data at each temperature points,the changing trend of the residual compressive strength of the resin from room temperature to 900℃and changing reason were analyzed.The test results indicated:at about 600℃,resin coking,with little variation in strength,at temperature higher than 600℃,the structure of the carbon in the resin samples changed,its strength rose slightly. |
