Text: The science and technology of composite materials

Warming-up:

1. What is a composite material?

2. What’s the difference between composite material and matter?

3. How could you define composite?

4. Do composite materials belong to the modern generation of materials?

5. Can you give any examples of composite materials?

1. bend(n) – излом, cгиб;bend(v) – bent-bent – сгибать,изгибать, гнуть

2. squeeze(n,v) – сжатие, сжимать, сдавливать

3. tear(n) – разрыв, разрез; tear(v)-tore-torn – рвать, разрывать, изнашиваться

4. snap(n) – трещина, треск; (v) – треснуть; (adv) – неожиданно, внезапно, вдруг

5. fracture – перелом, трещина излом; ломаться, раздробляться

6. compress(v) – сжимать, сдавливать

7. bind (v) – связывать

8. cluster(v) – тесниться;(n) – пучок

9. reinforce – укреплять, усиливать

2. Some modern terms derived from two words, for example, the term durability derived from the words “ during” and “ ability”. Analyze and try to translate the terms without a dictionary.

Model: Pultrusion derived from the words 'pull' (тянуть) and 'extrusion' (выталкивание) means вытягивание

flexibility, electroconductivity, thermo conductivity, thermosetting,thermosoftening, semiliquid, reliability, fiberglass, metalloceramics, organosilicon.

3. Analyze these words and their derivatives and translate them without a dictionary:

stiff – stiffen – stiffness; flex – flexible – flexibility – flexion; expose – exposed to – exposure – exposition; reinforce – reinforcement – reinforced by; compress – compressive – compression; tension – tensile – tense; tough – toughness – toughen;appropriate – to appropriate – appropriated for – appropriately; rely – reliable – reliability; align – aligning – alignment – by aligning;efficient – efficiency; immense – immensely; to reverse - irreversible – reversible – irreversibly – reversion; to bind – binder – binding; to mould – moulded into – by moulding – in the mould - moulder; rigid – rigidity.
