Specifying and describing properties

2.20 Pair work. Discuss what you know about the properties of Kevlar - and how it is used.

2.21 Read the following extract from DuPont""s technical guide to pare the information with your ideas from Exercise 2.20

WHAT IS KEVLAR®? DuPont™ KEVLAR® is an organic; fiber in the aromatic polyamide family. The unique properties and distinct chemical composition of KEVLAR® distinguish it from other commercial, man-made fibers. KEVLAR® has a unique combination of high modulus, toughness, abrasion resistance and thermal stability. It was developed for demanding industrial and advanced-technology applications. Currently, many types of KEVLAR® are produced to meet a broad range of end uses that require strong, lightweight, durable materials.

2.22 Find words in the text in Exercise 2.21 to match the following definitions.

1. _____________= the opposite of fragility

2. _____________ = resistance to damage caused by friction

3. _____________ = resistance to problems caused by temperature change

4. _____________ = long-lasting

5. _____________ = the opposite of heavy

2.23 Match the automotive parts (1-5) to the descriptions (a-e)

1  drive belts	a  sheets inserted between parts to prevent gas or fluid leakage
2  brake pads	b  pneumatic envelopes in contact with the road surface
3  tyres	с  flexible bands used in transmission systems
4  sealing gaskets	d  protective barriers capable of resisting gunshots
5  bullet-resistant armour	e  pads pressed against discs to induce deceleration

2.24 Read the information from DuPont" on the following page explaining some of the automotive applications of Kevlar'. Complete the text using the automotive parts in Exercise 2.23.

Car and truck (1) _______ have incorporated Kevlar® into their construction because it offers superb puncture, abrasion and tear resistance.

The high modulus and abrasion resistance of Kevlar® help (2) ______ retain their original shape and tension over the millions of revolutions they go through over the lifespan of a vehicle.

The frictional forces that (3) ________ are designed to endure take less of a toll on those made with Kevlar® pulp. The enhanced thermal stability and inherent abrasion resistance of Kevlar® allow them to last long and stop the vehicle safely and quietly.

Kevlar® provides an effective, lightweight (4) ________solution for vehicles that require protection against ballistic attack, allowing cars and light trucks to retain most of their original handling characteristics.

Chemical stability and thermal stability help to make (5)__________ reinforced with Kevlar® pulp strong and durable. The galvanic corrosion resistance of Kevlar® also contributes to improved long-term engine performance.

2.25 Match each application with the reason why the properties of Kelvar are important for them.

1. tyres	a) abrasion resistance help them to last longer
b) make it more light-weight which is better for  the vehicle’s performance
2. brake pads	c) thermal stability helps them to resist heat
d) high elasticity allows them to fit tightly
3. sealing gaskets	e) abrasion resistance helps them to resist friction caused by its turning
4. bullet-resistant armour	f) puncture and tire resistance help  to stop punctures and blowouts
g) thermal stability helps them to resist  the heat generated during the braking
5. drive belt	h) chemical stability  means that they are not affected by engine fluids, lubricating oil, and coolant liquids

2.26 Complete the table using new vocabulary of UNIT 2. Name the properties of each material

material	material properties	materials quality	what we can do with materials

2.27 Insert the correct material for watch-making. Using words from the box

Materials:  steel  glass  aluminium  titanium  gold  plastic copper  rubber

… is relatively heavy and tough. It’s pretty scratch-resistant and shock-resistant. …. …. is not very corrosion resistant, but … … has good corrosion resistance and is therefore suitable for watches. Ordinary …. is very brittle and has fairly  poor shock-resistance and scratch-resistance, although it’s suitable for watches. Toughened … is more durable. …. is relatively lightweight and is fairly tough, it has good corrosion resistance. …. is exceptionally lightweight and tough and has excellent abrasion resistance. It is also extremely corrosion resistant and is therefore an excellent watch material. …. is extremely heavy and pretty tough, although softer grades of it have quite poor shock-resistance and scratch-resistance. But it has also excellent corrosion resistance. It’s suitable for more expensive and decorative watches.

2.28 Choose any material, describe its properties and its appliance area.
