A process for producing a hollow structural component from fiber-reinforced plastic

For producing a hollow structural component from fiber-reinforced plastic is a water-dispersible supporting core of a water soluble binder, which consists at least partially of a water-soluble silicate-containing binder, and a filler is wrapped with the reinforcing fibers. The fibers on the support core are impregnated with a hardenable plastic, the plastic is cured and the support core then flushed with water.
