HAND LAY-UP
Hand lay-up is the simplest and oldest open molding
method of the composite fabrication processes. It is a
low volume, labor intensive method suited especially for
large components, such as boat hulls. Glass or other
reinforcing mat or woven fabric or roving is positioned
manually in the open mold, and resin is poured, brushed,
or sprayed over and into the glass plies. Entrapped air
is removed manually with squeegees or rollers to complete
the laminates structure. Room temperature curing
polyesters and epoxies are the most commonly used matrix
resins. Curing is initiated by a catalyst in the resin
system, which hardens the fiber reinforced resin
composite without external heat. For a high quality part
surface, a pigmented gel coat is first applied to the
mold surface.
