Manmade and Natural Materials

Students like myself need to know what materials are available, how

they behave in use and how they can be worked or processed during

manufacture and construction. Having a good understanding of these

will help me to select suitable materials for my products.

In choosing materials for a particular project, I will need to

consider their physical and working properties, so that I am able to

decide which material is best and which method of processing is

required in order to turn raw materials into finished products.

====================================================================

I have to use a procedure called product analysis. This involves

analysing and existing product in order to identify the materials that

have been used, the properties that make them suitable for the task

for which they have been designed as well as an awareness of the

processes used in their manufacture, construction and assembly. All

man-made materials are derived from one or several naturally found

materials.

History of materials

====================

Early human history is divided into eras named after the materials

that were predominantly used at the time. The Stone Age, Copper age,

Bronze Age and Iron Age suggest how important these materials were in

the development of early technology.

Early humans could only utilize the materials that they found to hand.

Stone, reeds, clay, wood, animal hides, hair and bone enabled them to

survive in otherwise inhospitable conditions. During these earliest

periods organic materials were by far the most important and useful.

Human resources were greatly enhanc...

... the way things look. I have to see if it will be fixed or if

it will be carried, as these factors could be very important. Weight

in the right place might be needed for balance and stability. I have

to look at how long a material will last before it is affected by its

environment, and how much energy the material can absorb.

After looking at all the information, and thinking about what

materials I use and how I use them, I have decided that the most

useful materials are natural. These were around at the beginning of

time when man didn't even exist. Apart from using these for products,

we eat them and use them in everyday life. If there wasn't wood to

burn for fire, there would not have been various man made materials.

Man-made materials are necessary in everyday life, but not as

necessary as natural materials.
