VERFAHREN ZUR HERSTELLUNG VON MODULAREN MASTEN UND MODULARE MASTANORDNUNG

摘要

There is provided a multi-layered composite article having an inner core of a first composite material and one or more than one outer layers of a second composite material, the second composite material comprising an aliphatic isocyanate polyurethane overlaying the inner core. A method of manufacturing such a composite article is also provided. The method comprises providing a core comprising a reinforcement impregnated with a first resin; mixing an aliphatic isocyanate component and a polyol component to produce a reaction mixture; impregnating a second reinforcement with the reaction mixture to produce an impregnated reinforcement; applying the impregnated reinforcement over an outside surface of the core; and allowing the reaction mixture to set to produce a composite article with one or more than one outer layers of aliphatic isocyanate composite material. The concentration of aliphatic isocyanate in the second composite material or in the reaction mixture is greater than the concentration of aliphatic isocyanate in the first resin or first composite material.
