Wet route

Wet route is the name given to the various composite part manufacturing processes in which resin is deposited in liquid form on the reinforcements during the manufacturing cycle.

There are many manufacturing methods based on the principle of the wet route, e.g.:

• contact moulding;
• spray-up;
• rotational moulding;
• low pressure injection (resin transfer moulding, RTM). ;
• la pultrusion;
• wet route filament winding..

Some processes such as winding can use both principles.

The depositing of resin on the reinforcements and their impregnation can be carried out manually (contact moulding) or mechanically by injection (RTM) or by dipping in a bath (pultrusion, filament winding).
