ABSTRACT:
A scratch resistant, flame resistant material is made by producing a sheet molding compound of a melamine-aldehyde precondensate, silica, alumina trihydrate, slightly soluble soap, ammonium hydroxide and acid salt catalyst. The sheet molding compound is applied to the surface of a pelt of glass fibers containing a heat curable binder and the composite is bonded together under heat and pressure to cure both binders simultaneously and bond the sheet molding compound to the fiber layer of the pelt.
