Hard and light at the same time
After mixing and curing, 2-component Epoxy Resins have a high impact resistance and are almost indestructible. That is why they are also used in the manufacture of fiber composite parts (e.g. GRP glass fiber or CFRP carbon fiber).
The manufacturing or processing of fiber-reinforced parts in series is also influenced by the fiber length.
Possible low-pressure processing methods are, for example:
- Hand Lamination
- Vacuum Lamination (VA-RTM)
- Wrapping
- Resin Transfer Molding (RTM)
- Pulltrusion
- Pressing
In the hand-laminating or pressing process, the resin/hardener mixture is poured onto a fiber mat, and then either
- cured in an open mold under temperature and time or
- in a press over pressure and temperature
giving the part the desired shape.
In the vacuum lamination process, the resin/hardener mixture is sucked from a reservoir into a closed or open mold with an inserted vacuum bag in order to penetrate the fiber mats inserted therein.
Lightweight components are used for a wide variety of industrial sectors and applications as in the automotive industry, aircraft construction or in the manufacture of rotor blades for wind turbines.
