Composite means: made from
up several parts
·
Composites are a combination of
2 or more materials
·
Usuallystiffreinforcements and a binder material (matwix)
Relevance for design
·
Properties are better than original materials:1 1 3 +

Properties can be fine-tuned in directions
different
Traditional composites (glass or carbon fiber laminates)
·
High strenght +stiffness
· Low weight
·
Tailored design
·
Good fatigue life
·
High dimensional stability
·
Good corrosion resistance
