Answer:
a. Composite materials are materials made from two or more different substances that are combined to create a new material with specific properties. They are often used in applications where a combination of properties is needed, such as high strength and low weight.
b. Carbon-fibre-reinforced plastic (CRP) is a composite material that is made from a combination of carbon fibers and a plastic resin.
c.
The advantages of using graphite in the manufacture of golf clubs include its light weight, which allows for greater clubhead speed and distance, and its ability to absorb vibrations, which can make the club more comfortable to use.
The advantages of using steel in the manufacture of golf clubs include its durability and resistance to wear and tear. It is also relatively inexpensive and readily available.
The advantages of using carbon fiber in the manufacture of golf clubs include its high strength-to-weight ratio, which can result in a more stable clubhead and increased accuracy, as well as its ability to be shaped and molded into complex shapes.
The main disadvantage of using graphite is that it is not as durable as steel, which means the club may need to be replaced more frequently.
The main disadvantage of using steel is that it is heavier than graphite, which can make it more difficult to generate clubhead speed and distance.
The main disadvantage of using carbon fiber in the manufacture of golf clubs is that it is relatively expensive compared to graphite and steel.
It should be noted that the choice of material for golf clubs also depends on the personal preferences and the intended use of the club.
