IX. Перепишите и переведите текст. Application of plastics in rolling stock

Many years ago rolling stock engineers paid attention to some properties of plastics in construction of different types of vehicles. Plastics have properties of particular value in rolling stock construction. Some of the most significant are: resistance to corrosive atmospheres, lightness, high strength, ease of manufacture and repair, thermal, sound and electrical insulation.

In appearance, the new vehicles do not differ greatly from other vehicles but in fact only a small proportion of the traditional construction is incorporated. The bodyshell is composed of longitudinal sections, each consisting of a sandwich construction with outer skins of aluminum and polyurethane foam core. The method of manufacture is to adhere glass fibres to the inner faces of the aluminum sheets, hold these in a mould and pour in a liquid polyurethane resin mixture. The bodyshell is thus light in weight, strong, rigid and thermally and acoustically insulated. The manufacturers estimate this method of construction to give a bodyshell 50 per cent lighter. Additional uses for plastics in these particular vehicles include luggage rack frames, window frames and interior panelling.
