Wet Lay-Up Moulding Processes Wet lay-up is a molding process that combines layers of reinforced fiber with liquid resin to create a high quality laminate.

Wet Lay-up Technique

This process involves the positioning of reinforcement material into or against a mold in layers. These layers are then impregnated with a liquid resin system, either with a brush or roller, to ensure a good wet-out of the reinforcement material. The step is repeated until reinforcement thickness is achieved.

Curing can be performed at room temperature or under heat, depending on the selection of the resin system. This can be accomplished with or without the use of a vacuum bagging process (recommended for a higher quality part).


Benefits of Wet Lay-up•    Easy processing
•    Low capital investment
•    Convenient for low-volume production
