Technical Details & Test Data
- Curing
The versatility of GMS Composites EP-350 means a range of cure cycles, pressures and ramp up rates can be adopted all of which will depend greatly on the part being produced. Below is a guide to cure cycles.
Temperature (°C) Time 100 4 hrs 120 2 hrs 140 1 hrs 150 30 mins - Heat ramp up rate – 2°C / min
- Pressure – 1 bar
- Gel Time
Hot plate
Temperature (°C) Time (min) 100 45-55 120 13-20 140 3-6 Values are indicative of small samples of neat resin formulation. Gel times may vary significantly in composites depending on fiber content and laminate thickness.
