Cure Terms Glossary
Hand lay-up is an open mould process in which an uncured composite is built up by hand in or on the mould. The manual operations may involve both resin impregnation (typically by brush or roller) and ply build up. Curing is normally at ambient temperatures, but may be accelerated by heating, if required (or feasible).
The process is normally
applied to large mouldings (boats, vehicle body parts, etc.) and the resin
component is likely to be either unsaturated polyester (commonly) or epoxy.
