Methods and systems for forming a thin-layer moisture-resistant fiber composite material involve pressing a mixture of fibers and resin between a pair of heated dies at least one of which includes a working surface coated with a hard ormosil coating including a cross-linked organically-modified silica network. The use of such coatings may yield composite sheet materials having improved surface quality, sharper edges, and greater draw angles than previously possible. Some systems for making thin-layer fiber composite materials may utilize ormosil coatings on various working surfaces of equipment coming into contact with the fiber and resin mixture, such as surfaces of machinery for mixing or conveying the mixture to the dies.
A method of forming a thin-layer moisture-resistant fiber composite material, comprising:
A system for manufacturing a thin-layer moisture-resistant fiber composite material from a mixture of cellulosic fibers and resin, comprising:
A composite sheet material product pressed from a mat of cellulosic fiber and resin, wherein the composite sheet material product has a sheet thickness of between 1 mm and 13 mm and is contoured during pressing to form at least one outside edge feature having an outside radius of less than 0.035 inch.
A composite sheet material product pressed from a mat of cellulosic fiber and resin, wherein the composite sheet material product has a sheet thickness of between 1 mm and 13 mm and is contoured during pressing to form at least one angled surface having a draw angle greater than about 70 degrees.
