Infusion resin dosing

Optimum cohesion for internal aircraft components

Rotor blades or aircraft wings must be able to withstand extreme loads and demonstrate high strength and rigidity. The infusion process ensures optimum cohesion of the internal components. This involves impregnating the semi-finished fibre products with infusion resin.

To do this, dry woven or non-woven (non-crimp fabrics/NCF) fibre materials are first placed in an open mould. A vacuum build-up is subsequently prepared to introduce the infusion resin. Infusion tubes and valves are then attached to the vacuum build-up. The main infusion tube is then connected directly to a metering system, which dispenses the infusion resin and applies it into the mould. The infusion can be performed either directly or via a buffer tank, which provides a constant flow of infusion resin. The DOPAG metering systems eldomix or compomix can be used to optimally dispense the material.
