Composite Manufacturing Methods
Hand layup (or wet layup) is any process where the laminator manually aplies the resin and the reinforcement. From there it can be rolled out and left to cure, or vacuum bagged. Hand layup requires that all the details and laminating features be accomplished before the resin starts to cure. This can really limit the amount of ta…

In the pultrusion process, wet fiber is pulled thorough a shaped die that is really hot. The fiber and resin goes in one end all goopy and comes out a fully cured part. Like extrusion (which is a push process), pultrusion (a pull process – can't push on wet fiberglass!) produces long things with a consistent sectional shape.
