Prepreg is the basic process of impregnating a technical fabric (glass, carbon, aramid, etc.) with a resin and converting a prepreg. This process is used for Advanced Structural Composites, Printed Circuit boards (Copper Clad Laminates – CCL) and various other Laminates. Prepreg can be for woven or non-woven webs, paper, or unidirectional tows to make tape. The resins used in the Prepreg Line primarily use organic solvents in the dip, and require special safety systems for the processing and handling of solvents.
Pathsfinder Prepreg machine is equipped with:
- Vertical or horizontal heating / evaporating system depending on the resin being used
- Fabric machines can be either vertical or horizontal
- UD solution machines are normally horizontal
Fabric Prepreg Treating Woven fabric prepreg can start with Glass, Carbon, Aramid, and other textiles. Typical widths start at 12” (300 mm) and go up to 50” (1270 mm) based on available weave widths. The ovens can be vertical or horizontal depending on the space available for the customer.
Web Handling – unwinds, rewinds, tension control
- Unwinds and rewinds feature safety chucks for safe operation and precise tension control
- Custom designed to accommodate the package sizes and desired speed and tension requirements
Resin Application – Impregnation Station and Metering Rolls
- Resin application is through doctor roller or metering roller system to ensure application of proper amount of resin on the fiber.
Generally, a dipping process followed by a set of precision doctor rolls. The doctor rolls set a finite gap and remove the excess material to achieve the proper resin content weight.
