6. How are composite materials with ceramic and metal matrices called?

7. What are the advantages of composites?

8. What are the disadvantages of composites?

9. Why anisotropic properties of composites should be taken into account?

8. Find equivalents in the text:

1.композитні матеріали

2.унікальні механічні якості

3.полімерні матричні композити

4.складати 60% об'єму

5.привабливі якості

6.структура, що піддається дії різно-направлених сил

9. Translate into Ukrainian:

1. PMC is fabricated so that all the fibres are lined up parallel to one another.

2. Forming strong connections between separate composite material components is difficult.

3. Fabricating composite materials is a complex process.

4. Composite materials have certain advantages over conventional materials.

5. Nowadays, composites are being used for structures such as bridges, boat-building etc.

10. List as many car systems as possible. Compare your list with the

rest of the group. Who's got the longest list?

What is the fuel system used for?

11.Philip, a student of Automotive Engineering, has met his friend Alex in

the laboratory testing. Listen to their dialogue and learn the basic principle of the carburettor operation.

Philip: Hello, Alexl What are you doing?

Alex: Well, I'm studying the fuel system of this car. Now I can tell you a lot about the basic principles of its operation.

Philip: Really? O.K. Let me see. Do you know the name of that little device near the engine?

Alex: Sure, it's called a carburettor.

Philip: And what is it used for?

Alex: Well, it measures out a precise amount of fuel that is mixed with the correct amount of air.

Philip: And do you know the principle of the carburettor operation?

Alex: Oh, that's easy. First, air is drawn down the air intake (it is located directly above the carburettor) into a venturi where its pressure is lowered. That's why, the fuel will flow into the venturi.

Philip: Will it flow because of the low pressure of the air?

Alex: Right you are. Then the air is mixed with the fuel before this mixture is taken into the cylinder combustion chamber.

Philip: Is it really? And what happens with this fuel mixture in the cylinder combustion chamber?

Alex: It is ignited there and is drawn into the engine afterwards.

Philip: I see.

12. Complete the dialogues.
