MULTI-LAYER PROCESS FOR PRODUCING HIGH STRENGTH FIBER-REINFORCED STRUCTURAL CEMENTITIOUS PANELS
摘要
<p>A structural cementitious panel, produced by a multi-layer process including providing a moving web; b. one of depositing a first layer of loose fibers upon the web and c. depositing a layer of settable slurry upon the web; d. depositing a second layer of loose fibers upon the slurry; e. embedding said second layer of fibers into the slurry; and f. repeating steps c. through e. until the desired number of layers of settable fiber-enhanced slurry in the panel is obtained. Also provided are an apparatus suitable for producing structural cementitious panels according to the present process, and a structural cementitious panel having multiple layers, each layer created by depositing a layer of settable slurry upon a moving web, depositing fibers upon the slurry and embedding the fibers into the slurry such that each layer is integrally formed with the adjacent layers.</p>
