Fiberglass direct rovings are immersed in a resin bath where they are coated with resin system. The impregnated tows are then literally wound around a mandrel (mold core) in a controlled pattern to form the shape of the part. After winding, the resin is then cured, typically using heat.
To achieve best mechanical and dielectric performance and good wetting, predrying of fibers is advised.
For good wetting of fibers and reproducable quality results it is recommended to warm up the impregnation batch to 30 - 40°C.
Temperature of the mandrel should be 60 - 90°C, preferred 70 - 80°C. With this setup gelation should occure from inner layers to outside layers, a good de-air will be achieved and
shrinkage minimized.
Resin is optimized for easy degassing.
Usuable potlife of the mixed resin is > 1 shift (8 h) at 25°C and 40°C.
After impregnation and winding curing of the part should start as fast as possible, as the hardener in the reactive mixture is sensitive versus moisture.
Cure: 4 h 80 °C + 8 h 140 °C (standard lab condition)
