【Abstract】 Aim\ To research TDE-85/DDS system, find the curing method and mixing method. Methods\ The viscosity, gel time and DTA curves of the system and the properties of E-GF reinforced composite material with it are measured by experiments. Results\ The curing condition is 100 ℃/2 h+130 ℃/3 h+170 ℃/3 h+220 ℃/3 h and the melting-overcooling method is proved to be the best mixed method. Conclusion\ TDE-85/DDS system is the suitable matrix for vapor assisted resin transfer molding and the properties of GFRP equilibrium tube have exceeded the technical-demands.更多还原
