| Abstract: | Three room temperature-curable epoxy candidate resins with low viscosity:QC350A/B,1564/HY3487,EV6620/HVC188 were characterized for rheological properties,degree of cure for different time in room temperature and room temperature cured flexural properties. The results indicate that three epoxy resins exhibite a long-term stable resin transfer moulding operating platform in 20-50℃. The degree of cure reach 90%after been cured at room temperature for different elapsed times. The flexural strength of samples cured at room temperature for twenty-one days is comparable to the samples cured at higher temperature. The flexural modulus of samples cured at room temperature for twenty-one days is superior to the samples cured at higher temperature. So the mechanical properties of candidate resins cured at room temperature met the requirements when used as structural parts. |
