Composite Materials

Which of the following is not a composite material

• MDF

• Carbon fibre

• Arimid fibre

• Structural concrete

• Glass

In CFRP the carbon fibres are know as the

• Matrix

• Reinforcement

• Filler

• Structure

In GRP the bonding material is known as the

• Matrix

• Reinforcement

• Filler

• Strengthener

The bonding material used in glass reinforced plastic (GRP) is a

• Thermosetting plastic

• Glass resin

• Thermo plastic

• Natural resin

An important property of polymer reinforced composite materials is?

• Hardness

• Compression strength

• Strength to weight ratio

• Conductivity

One benefit of using a composite material in manufacturing is that they

• Look smart.

• Have good electrical conductivity.

• Are cheap.

• Can easily be produced into complex shapes.

Which of the following is not a production process used in the manufacture of composite products?

• Wet layup/lamination

• Filament winding

• Spraying

• Vacuum forming

Which of the following pieces of equipment would commonly be used in the manufacture of CFRP products?

• Wooden spoon

• TAGS welding machine

• Lathe

• Autoclave

An advantage of using GRP in the production of a large range of products is that

• Colour pigments can be added to improve the ascetics of the product.

• It is a very cheap material so that the product cost is low.

• It is a heavy material so products being used outside wont get blown away.

• It has got good compression strength so wont get squashed in use.

The chain structure of the thermosetting resin used in glass reinforced plastic would be?

• Cross linked

• Branched

• Linear
