Abstract: A method of making a polymer coated rail in which a rail to be coated (10) is positioned on a mould base (11) in an inverted manner, so that the head (12) of the rail is immediately adjacent the base plate (11). Then, mould side pieces (13, 14) are secured to the base plate (11) to run parallel to the side of the rail (10). Antislip material such as bauxite or granite chippings (21) are positioned in the mould so that they lie on the base plate (11), and then the liquid polymer is poured into the mould to fill the spaces (19, 20) and so encapsulate the rail (10). The polymer is poured into the mould, until its surface (22) covers the foot (23) of the rail. In this state, the polymer is allowed to cure, so that it solidifies, and once the side plates (13, 14) have been removed, the rail together with its polymer coating can be lifted from the base plate (11).
Abstract: A composite material resistant to armour piercing bullets consisting of a highly elastic polyurethane matrix into which is embedded aggregate, preferably in the form of rounded pebbles having an average screened size range of from about 20 mm to about 60 mm.
