composites

Question 1

what are some composites?

Answer 1

aluminium composite board
GRP - glass reinforced polymer
CFRP- carbon reinforced polymer/epoxy
Tungsten carbide
concrete
reinforced concrete
fibre concrete
engineered wood like glulam

Question 2

aluminium composite board uses?

Answer 2

signage
sound proofing panels in cars

Question 3

aluminium composite board properties?

Answer 3

lightweight
sound and thermal insulation
vibration damping - prevents it from travelling
tough
malleable

Question 4

what is aluminium composite board made from?

Answer 4

aluminium sheets with a polyethylene core

Question 5

what are the type of concrete composites?

Answer 5

normal with powder, sand, rocks (aggregate particles) and water

reinforced with the addition of low carbon steel rods

fibre with polymer or steel fibres

Question 6

concrete properties

Answer 6

high compression strength
easy to mould
few surface defects
low tensile strength

(this increases in reinforced and fibre)

Question 7

tungsten carbide:

Answer 7

mixture of ceramic tungsten and cobalt metal

hard, tough and temp resistant, corrosion resistant

cutting tools such as drill bits and lathe tool tips

Question 8

GRP and CFRP properties

Answer 8

lightweight, corrosion resistant, tough and hard.

good compressive strength and low thermal expansion.

Question 9

GRP uses?

Answer 9

sports car bodies and parts
boat hulls

Question 10

CFRP uses?

Answer 10

sports equipment like bicycles
