Abstract:This paper introduce a new R602 resin system for room temperature RTM process, which have low
viscosity, high reaction activity and good properties. The resin began to gel at 105℃, to cure at 125℃ and to handle
for better properties at 175℃, the Tg is 178℃. R602 resin system have low viscosity at room temperature and its potlife
is more than 50 hour. The cured resin and composites of R602 resin system also exhibit excellent mechanical properties
and hygroscopic resistance property. The tensile strength of the cured product is 97. 2 MPa, fracture elongation
percentage is 4. 12%, and flexural strength is 162. 6 MPa. In addition, the SEM reveal that the impregnation of the
R602 resin to fiber is very good.
