c6.1.14 composite materials Flashcards
composite materials
2 or more materials of different properties put together to create a new material
polyester-cotton- how is it made?
weaving the cotton thread into polyester fibre
polyester-cotton- properties
it is more hard-wearing than cotton alone and easier to wash and dry
Resin to fibreglass- properties of fibre
low density
high tensile strength but BRITTLE
Resin to fibreglass- properties of resin
hard-wearing but not STRONG
Resin to fibreglass- how is it made
Glass fibres in a resin
Concrete- made from
Sand and concrete
Concrete- properties
High compressive strength but
low tensile strength and it breaks if heavy load is put on top of it
Concrete- embedding steel rods in
Gives it a high compressive strength
High tensile strength
Plywood- structure
Layers of wood are glued together where the grain is at 90 degrees to the grains in the layer underneath it
