Metal Foam

When we think about dangers to our health, we usually think of dangerous
diseases. However, one of the leading causes of death around the world is trafficaccidents. In fact, traffic accidents are the biggest cause of death for people aged
15 to 29. Furthermore, not only do 1.2 million people die in such accidents everyyear, but 20 to 50 million people are also injured. While some wealthy countries
have reduced the number of traffic accidents in recent years, they are increasing
rapidly in developing countries.

One way to deal with this problem is to make cars that are better able to protect,the people inside them during accidents. For many years, the researchers havebeen interested in using metal foam to do this. Metal foam refers to a metal,
usually steel or aluminum, which has had bubbles of air or another gas inserted
into it. Usually the metal foam between 75 to 95 percent air. This makes it very
light compared to ordinary metal. Metal foam have been created for some time,
but most them have been very weak. This has made it difficult to use them invehicles.
Further Questions & Sample Answers3) What is one way to deal with traffic accidents?
3) To make better cars that are able to protect the people by using a metal foam.
4) What is a Metal Foam?
4) It refers to a metal usually steel or aluminum, which has bubbles of air.
Afsaneh Rabei, a scientist at North Carolina State University in the UnitedStates has developed a new metal foam. Rabei spent five years developing it.
According to her, the problem with earlier metal foams was the bubbles werevarious sizes. In the new metal foam, though the bubbles are in regular insize. This results in a much stronger metal foam. Test carried out by Rabei
show that the new material is five to six times stronger than other metal
foams and also greatly decreases the damage that occurs in crash. Thismeans that, if it were be used to build cars, it would be much better thanordinary metals at protecting drivers and passengers. Rabei believes thatnew metal foam could also be used in boats and airplanes, as well as to help
protect buildings against earthquakes.

1 leading to more people having dangerous diseases.
the main cause of death for people of all ages in wealthy countries
becoming more and more of a problem in developing countries
usually caused by drivers who are between the ages of 15 and 29.

52(31) What is one problem with most type of metal foam?

5356

1 They are not strong enough to improve the safety of cars.
2 They are made of aluminum which is too light use in cars
3 The steel that is used to make them is not filled with enough bubbles
4 The air inside causes environmental damage when it is released.

57(32) What has Afsaneh Rabei developed?

58

61

1 A way to release the unnecessary bubbles from metal form
2 A type of metal foam in which each of the bubbles is the same size
3 A stronger type of metal that can be used to create better metal foam.
4 A quicker way to produce the metal that is used to create metal foam.

62(33) What is one possible benefit of Rabei’s new material?

63

1 It can reduce the damage and injuries that result from car crashes.
2 It can be used to prevent a large number of earthquakes
3 It may allow companies to build cars that are five to six times cheaper
4 It may also decrease the number of boat and airplanes accidents that occur.
