VI a) Прочитайте текст и ответьте на вопрос What developments marked the beginning of the modern era of

composite materials?

ADVANCED COMPOSITE MATERIALS

1. Composite materials are among the oldest and newest of the materials alone. Following this principal they combined clay and straw to make bricks. Then with some notable exceptions, the further potentialities of composite materials remained virtually untapped for centuries while monolithic materials, such as iron and copper, served the major needs of an advancing technology. Even in the more recent times with coming of reinforced concrete, linoleum, plasterboard and plywood panels were somewhat out of mainstream of materials development and technology.

2. During this 1930’s and 1948’3, however, light-weight honeycomb structures, machine parts from compressed metal powders and plastic reinforced with glass fibers became commercial realities. These developments marked the beginning of the modern era of composite engineering materials. The use of composite materials is steadily growing. The consumption of the fibre reinforced plastics, for example, is increasing at the phenomenal rate of 25 per cent annually.

3. There are two major reasons for the current interest in composite materials, The first is simply the demand for materials that will outperform the traditional monolithic materials. The second, and the more important in the long run, is that composites offer engineers the opportunity to design totally new materials with the precise combination of properties needed for a specific task and use them more sparingly because of their superior quality.
