composite materials / modern materials Flashcards
what are composite materials
a material made up of 2 or more materials to enhance the properties of the new material
list 6 composite materials
-reinforced concrete
-laminated wood
-carbon fibre
-ceramic matrix
-steel
what are smart materials
smart materials are materials that change their properties due to an external stimuli then changes to the original afterwards
list 6 smart materials
-shape memory alloys
-thermochromic pigment
-phosphorescent pigment
-photochromic pigment
-electroluminescent wire
-peizoelectric material
what are the main properties of tungsten carbide
extremely hard, rigid and impact resistant
what is tungsten carbide used for
-high speed cutting tools which get hot due to friction
-premium kitchen knifes
-surgical instruments
-jewellery
what are the properties of carbon fibre
-directional force
-lightweight to strength ratio
-high tensile strength
what is carbon fibre a combination of
carbon fibre and resin ( such as vinyl ester and epoxy
what are the resistant properties of carbon fibre
-corrosion
-chemical
-largely thermal
what are the main applications of carbon fibre
-premium cars
-wind turbines
-bike frames
is glass reinforced plastic (GRP) a thermoset or thermosetting plastic
thermosetting (polyester or epoxy are combined with glass fibres
what are the properties of GRP
-strong in tension with little compressive strength
-lightweight
-thermal insulation
what is GRP used to make
-boats
-car body panels
-sculptures
what is one advantage of GRP over carbon fibre
cheaper than carbon fibre
what is aluminium composite board
it is a composite sheet material combining a polymer core faced with a thin sheet of aluminium
