6. These are answers to the questions about the text. Write the questions.

1. Composite materials usually have unique mechanical and physical properties because they combine the best properties of different materials.

2. Composites are used for structures such as bridges and boat-building.

3. The most widely used type of composite material is polymer matrix composites (PMCs).

4. Composites can also have other attractive properties, such as high thermal or electrical conductivity and a low coefficient of thermal expansion.

5. The advanced composites have high manufacturing costs, a complex process of fabricating composite materials.

6. Are the following sentences true or false? If they are false correct them.

1. None ferrous metals have unique mechanical and physical properties because they combine the best properties of different plastics.

2. Composite materials usually consist of synthetic fibers within a matrix, a material that surrounds and is tightly bound to the fibers.

3. Composites with metal matrices or ceramic matrices are called ceramic matrix composites (CMCs) and metal matrix composites (MMCs) , respectively.

4. The specific strength (strength- to-density ratio) and specific stiffness (elastic modulus- to-density ratio) of continuous carbon fibre PMCs, for example, can be better than metal alloys have.

5. Forming strong connections between separate composite material components is simple.

5. Translate into Russian the third paragraph starting with the words

Continuous-fiber composites are generally required for structural applications… up to the words must take these anisotropic properties into account.
