Transcript of Materials and compoents

As a designer, you need to know about the properties of a wide range of materials and components so you can make informed choices about their use in certain products. What is the best material for a bike frame, for instance - aluminium or carbon fibre?

Would the sales of a product like a lawn mower increase if it were manufactured from a lightweight material such as aluminium rather than plastic? Designers have to make these decisions with every product they design.

In this section you will need to develop knowledge and understanding,where appropriate, of the aesthetic, functional and mechanical properties of resistant materials.
Getting started
Materials and compoents
The sensory qualities of a material
Aesthetic properties
The qualities a material must possess in order to be fit for purpose,for example the correct weight, size, etc.
Functional properties
A material's reaction to physical forces, e.g. strength, plasticity, ductility, hardness, brittleness, malleability, etc.
Mechanical properties
Very often specific terms are used to describe particular properties of materials. A good understanding of those terms is necessary for a full understanding of the materials involved in Resistant Materials.
Terminology
The ability of a material to return to its original shape once the deforming force has been removed.
Plasticity
The ability of a material to be drawn or stretched
Ductility
Ability of a material to withstand indentation, abrasion or scratching.
Hardness
The ability of a metal to be deformed by compression without being torn or cracked.
Malleability
The tendency of a material to fracture under stress.
Brittleness
