- Abstract
In order to achieve a superior overall mechanical performance of carbon fiber (CF) composites for demanding aircraft applications, innovative epoxy resin system was studied and applied to satellite antenna successfully. The proper proportion of three amine curing kinetic parameter, mechanical properties and heat resistance of casting parts were studied by means of DSC, DMA and mechanical property experiment. Furthermore, mechanical properties, hest/cold resistance and irradiation resistance of these CF composites were investigated. From the orthogonal analysis result, it is found that the best proportion of three curing agents was 15:10:6. The results indicated that the formulation of the epoxy resin matrix has low viscosity, longer-life-time and better heat resistance property. Through the high/low temperature and irradiation tests, the compression strength of CF laminates reduced 30% and 8% respectively. However, compression modulus, bend and tensile mechanical property of laminates were equivalent or greater than which before tests. The results not only showed CF composites has comprehensive properties, but also showed the epoxy resin matrix has strong interfacial adhesion with the carbon fiber.
