Big Question: What skills are required to be successful and to achieve excellence in GCSE Product Design?

Materials can be split into 5 main categories; Woods, Plastics,

metals, composites and smart materials.

LO2: TBAT to identify and explain a range of materials and their associated characteristics.

You DO NOT need to know about every single material, however you

do need to know at least TWO materials and SOME of their

characteristics for each category.

We will focus on Woods, Plastics and Metals today.

MANUFACTURED WOODS




MDF - Smooth, even surface.

Easily machined and painted or stained.

Plywood - A very strong board

which is constructed of layers of veneer or piles which are glued at 90 degrees to each other.

Chipboard - Made from chips

of wood glued together. Usually veneered or covered in plastic laminate.

Uses

Uses

Uses

Used mainly for furniture and interior panelling due to its easy machining qualities. Often veneered or painted.

Used for strong structural panelling board used in building construction. Furniture making. Some grades used for boat building and exterior work

Used for kitchen and bedroom furniture usually veneered or covered with a plastic laminated. Shelving and general DIY work.

Woods made by gluing wood layers or wood fibres together. Manufactured boards often made from waste

material.


Advantages: Much cheaper than solid wood, available in larger widths, has a consistent strength across the material

Demonstrate

Memory Challenge: In pairs you will test in each on the different types of woods discussed.

Rules of Challenge : • Challenge time is 15 minutes.

• Pairs will label themselves A or B.

• You both have ONE minute to re-read the information on a revision card.

• A’s will go first and ask B’s questions about what they have just read. (One minute)

• B’s will then ask questions to A’s about what they have just read. (One minute)

• This will be done until the pairs have gone through all the revision cards

• After the 15 minutes the teacher will give each student an exam question on woods to answer in SILENCE (5 minutes)

There are two types of plastic; thermosetting plastics and

thermoplastics.

Thermosetting plastics once heated and moulded can NOT go back

to its original shape. (Difficult to recycle)

Thermoplastics

ACYRLIC- This is the most common plastic in a school workshop. Purchased in the form of sheets and comes in a range of

colours. Easy to cut shape. Polishes well.

HIGH IMPACT POLYSTYRENE (HIPS)-Light material and yet strong. Available in a

range of colours. Can be vacuum formed. Thinner HIPS is quite flexible.

POLYPROPYLENE

Thermoplastic often formed into products through injection and blow moulding.

It is robust, strong, flexible and supplied in a range of colours

Thermosetting plastics

POLYESTER RESIN- Resins are

combined with materials such as ‘fibre glass’, the result is a very tough material that can resist impact. Known as Glass

reinforced Plastic.

MELAMINE FORMALDEHYDE- Smooth and hygienic qualities, used

for kitchen laminate surfaces.

UREA FORMALDEHYDE- Has high hardness and toughness, so its

suitable for strong, knock-resistant electrical fittings. Scratch resistant,

very good electrical insulator.

Uses

Uses

Uses

Car body repairs, sailing boats and airplanes.

Electrical plugs and sockets, because it can be cast and is

an excellent insulator

TV cases, plugs, refrigerator case

Activate

There are two different types of metals. Ferrous and Non-Ferrous metals.

Ferrous metals contain iron. Therefore they rust easily and are magnetic Non-ferrous metals DO NOT contain iron. Therefore do not rust and are not magnetic.

ALUMINIUM- Light grey in colour. Mixture of: 95% Aluminium, 4%

Copper,, 1% Manganese.

Ductile, soft , light weight and resistant to corrosion

Uses Used widely in aircraft, drinks cans, window frames, ladders,

and kitchen ware.

COPPER- Darkens slowly when in contact with air.

Ductile, can be beaten into shape as it is relatively soft. Conducts

electricity and heat.

Uses Electrical wiring, tubing, kettles, bowls, pipes and

plumbing. Used also in the production of printed circuit

boards

PEWTER-Pewter is a soft. It is an alloy consisting of copper , lead, tin

and other metals. Has a low melting point compared

to many metals making it highly suitable for casting.

Uses Used for making fashion

jewellery and other decorative pieces

MILD STEEL- A ferrous metal is a metal that contains iron. Mild steel is used to

manufacture a range of steel products.

Uses

Car bodies, general parts for machines, steel tube, chains

and many more

STAINLESS STEEL- Alloy of iron, nickel and 10.5% to 11% chromium.

Tough, resistant to rust and stains.

Does not corrode.

Uses Cutlery, medical instruments. Stainless steel pots and bans.

Jewellery and watches.

Ferrous metals can be considered as an ALLOY.

Alloys are metal that are combined with other substances resulting in superiors properties such as; strength, hardness, durability,

toughness and tensile strength.

IRON- A ferrous metal is a metal that contains iron. Mild steel is used to

manufacture a range of steel products.

Uses

Car bodies, general parts for machines, steel tube, chains
