Compositie Materials Flashcards
What is the main material in CFRP and GRP
Polyester resin, although epoxy can be used, the use of these two give the CFRP strength and rigidity
What is CFRP
Carbond fibre reinforced plastic
What is GRP
Glass reinforced plastic
Talk about CFRP
lightweight
corrsion restsnce
tough
hard
good compressive strenght
low thermal expansion
Talk about carbon fibres
High tensile strength
Alone they are strands
When mixed with reisn they become strong and rigid
Good strength to weight ratiio
Talk about glass fibres
Lower cost than carbon
Loose strands
Mixed with resin in a mould to form
Time consuming process
Used in one off situation
What are composite materials
Materials made from two or more ‘ingerdients’
uses of cfrp
