| Processing methods | Thoroughly mix components A and B at 25°C in a 1: 0.434 weight ratio. The error in the dosage of components should not exceed 2%. Particular attention should be given to mixing at the walls and bottom of the mixing tank. It is recommended to use devices 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, between the layers of the vacuum film airweave should be laid . Carry out a leak test of the second vacuum bag. The residual pressure in the bag must not be more than 10 mbar. Maintain temperature at 25-40°C. The recommended impregnation temperature is 25-35°C. It is recommended to preliminarily dry the reinforcing material in vacuum bag at 60-80°C for at least 1 hour. Maintaining the temperature of the mold at 25-35°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 (~24h at 25°C). After 48-72 hours, you can remove the part from the mold and post-cure without mold. Post-cure: Increase the temperature at a rate of 2°C/h to 80°C, keep it at 80°C for 6 hours. Curing is allowed immediately after the impregnation process without being removed from the mold. Increase the temperature at a rate of 2°C/min to 80°C, exposure at 80°C for 6 hours. Before removing the part, cool the tooling to at least 50°C at a speed of no more than 5°C/min. Curing (heating rate 2°C/min) or post-curing (heating rate 2°C/h) to 120°C is permissible to obtain a glass transition temperature of 140°C. | |
