摘要：: <p>An improved process for the manufacture of shaped articles from water-hardening materials reinforced with multiple layers of a fibrillated organic film. A plurality of networks are formed from fibrillated organic films and are simultaneously advanced into contact with a water-hardening material to form a composite layer of the networks impregnated with the water-hardening material. This layer is thereafter formed into the desired configuration for the shaped article, and allowed to set. The average number of meshes within the networks with a minimum of two per square centimeter and the number of networks within the layer are such that the average number of meshes per cubic centimeter of the final shaped article is at least 100.</p>
