Flashcards in Composite Materials Deck (10):
What is a Composite Material?
Material made from 2 or more different materials, with different properties to those of the materials
What do many Composite materials consist of?
Fibres embedded in a polymer resin
Why do many composite materials consist of fibres embedded in polymer resin?
Fibres have low density and high densile strength but are brittle
Resin is hardwearing but not strong
Means material is strong, lightweight, hard
What does Fibreglass consist of?
Glass fibres in resin
What does carbon fibre consist of?
Carbon fibres in resin
What does Concrete consist of?
Aggregate (small stones)
Water is added to bind ingredients together
What are the properties of Concrete?
High compressive strength
Low tensile strength
What material is embedded into Concrete to increase the tensile strength?
makes Steel-reinforced concrete with high compressive strength and high tensile strength
What is Plywood?
A composite material with thin sheets of wood glued together in layers
Grain in each layer is set at right angles to layer below
