Fiber composites are combinations between reinforcing fibers and plastic matrix, which consist mainly of reactive two- or multi-component polymer systems – both thermosets such as epoxy and polyurethane systems and thermoplastics such as in-situ polymerizable polyamide systems.
Meter mix dispense technology from Mahr Unipre is used especially when high meter mix dispense precision is required. This is the case within the production chain of composites with reactive polymer systems, as in the following examples:
- Production of fibre matrix semi-finished products such as prepreg and SMC
- Direct and continuous filament impregnation process (pultrusion and filament winding)
- Direct resin injection/resin infusion processes such as RTM, VA-RTM, T-RTM
