Application areas | The resin can be used for manufacturing CFRP or GFRP with sustainable properties up to 120°C, or for composite tooling with service temperatures up to 180°C. | |
Processing methods | Thoroughly mix components A and B at 25°C in a 1:0.4388 weight ratio. It is recommended to use device with automatic mixing and mix under vacuum. Degas the resin with intensive mixing for 15-30 minutes at 20-25°С, pressure no more than 10 mbar. Assemble vacuum bag. Perform a leak test, the rate of the vacuum loss should not be more than 1 mbar per minute. The residual pressure in the bag must not be more than 10 mbar. Assemble the second vacuum bag. Carry out a leak test of the second vacuum bag with same conditions. The recommended impregnation temperature is 25°C. It is recommended to preliminarily dry the reinforcing material in a vacuum bag at 60-80°C for at least 1 h or 6 h at 25°C. Maintaining the temperature of the mold at 20-30°C, start the infusion process. After complete impregnation, close the resin inputs, continue evacuation from inner bag for at least 30 minutes at 25-40°C. Close the outputs from the inner bag. Continue evacuation from outer vacuum bag until gelation (~24 h at 25°C). After 48-72 hours, you can remove the part from the mold and post-cure. Post-cure: Increase the temperature at a rate of 5°C/h to 80°C then at rate 10-15°C/h to 180°C, dwell for 1 hour (or with step mode same as in picture). Highest mechanical properties of CFRP are achieved at a temperature of 80-120°C. When cured at higher temperatures, a higher heat resistance is achieved with a slight fall in the mechanical characteristics of the CFRP. |
