CORRECT ANSWERS
GRADED A+ LATEST 100%
GUARANTEED PASS
Smart materials - CORRECT ANSWER-Have a property that changes in response to an external
stimulus. This change is reversible if the stimulus changes again
Composites - CORRECT ANSWER-Combine the properties of two or more materials
Composite property - CORRECT ANSWER-Unlike an alloy they are not mixed together
Glass-reinforced polyester (GRP) - CORRECT ANSWER-Used in car body building
Carbon-reinforced polyester (CRP) - CORRECT ANSWER-Used to make tent poles and sports
equipment
Where do composites go after their usable life? - CORRECT ANSWER-Landfill
Purpose of finishing - CORRECT ANSWER-Improve functionality or aesthetics
,Powder coating - CORRECT ANSWER-A powder is sprayed onto the metal, and the powder and
coat are electrically charged to attract an even coat and then heated
Polishing - CORRECT ANSWER-Includes cutting the surface of the material until it is very smooth
Paints - CORRECT ANSWER-Can be applied with a brush or sprayed onto a material
Natural fibres - CORRECT ANSWER-Come from animals or plants
Animals fibres examples - CORRECT ANSWER-Wool and silk
Plants fibres examples - CORRECT ANSWER-Cotton and linen
Property of natural fibres - CORRECT ANSWER-Biodegradable
Alloys - CORRECT ANSWER-Mixtures of two or more metals
Purpose of alloys - CORRECT ANSWER-Designed to have better properties for an application
than using the pure metal
Brass (alloy) - CORRECT ANSWER-Copper and zinc
Stainless steel (alloy) - CORRECT ANSWER-Iron and chromium, with a small amount of carbon
Brass property - CORRECT ANSWER-Corrosion resistant
, Stainless steel - CORRECT ANSWER-Tough, strong and hard
Technical textiles - CORRECT ANSWER-Manufactured for performance properties rather than
visual appearance
Technical textile example - CORRECT ANSWER-Kevlar in body armour provides protection from
weapon impact
Casting - CORRECT ANSWER-Can be used to make 3D products from metal
How can CAD files be shared? - CORRECT ANSWER-Email, intranets, USB memory sticks or via
the cloud
Advantage of CAD - CORRECT ANSWER-Can be viewed from different angles and is extremely
accurate
Disadvantage of CAD - CORRECT ANSWER-Some CAD products are expensive to buy, so there
can be initial setup costs
Extrusion - CORRECT ANSWER-Process used for manufacturing long and straight metal parts
Shape of the cross-sections formed in extrusion - CORRECT ANSWER-Solid round, rectangular, T
shape, L shape and Tubes
Extrusion process - CORRECT ANSWER-Done by squeezing the metal in a die by using a
mechanical or hydraulic press
Benefits of extrusion - CORRECT ANSWER-Cost effective because it minimises the need for
secondary production
