Fiber spraying represents an automation and further development of the laminating process. In this process, a mixture of cut fibers (roving) and resin is injected into the open mold by means of a spray gun. Before the resin cures, it is compacted and deaerated with a roller – similar to hand lamination.
Fiber spraying is frequently used in the production of predominantly large-area series parts made of GRP (e.g. boat parts, swimming pools, catch basins, tanks). A major advantage of this technology compared to hand lay-up processes is a lower craft content and a high material yield.
