Composite Materials
Question | Answer |
---|---|
What is a composite material? | A composite material is a combination of two or more materials to improve and change physical properties. |
Name examples if Composites. | GRP (Fibreglass), Carbon Fibre, CFRP, Tungsten Carbide, Aluminium composite board and Concrete. |
State the component materials in CFRP (Carbon Fibre Reinforced Polymer). | Carbon fibres mixed with polyester resin. |
What are the properties of CFRP? | Lightweight, corrosion resistant, tough, hard, low thermal expansion, good compressive strength. |
What are the uses of CFRP? | Sports equipment = bicycle frames, racing car bodies, helmets |
State the component materials in GRP (Glass Fibre Reinforced Polymer). | Class fibres mixed with polyester resin. |
What are the properties of GRP? | Lightweight, corrosion resistant, tough, hard, low thermal expansion, good compressive strength. |
What are the uses of GRP? | Kayak shells, sports car bodies and locomotive train cabs. |
State the component materials in Tungsten Carbide. | A cermet (mixture of ceramic and metal particles). Ceramic tungsten and cobalt metal. |
What are the properties of Tungsten Carbide? | Hard, tough, resistant to high temperatures, corrosion resistant. |
What are the users of Tungsten Carbide? | drill bits, kitchen knives and router bits. |
State the component materials in Aluminium composite board. | Aluminium sheets with a polyethylene core. |
What are the properties of Aluminium composite board? | Lightweight, rigid, tough, malleable, good thermal and sound insulation, good vibration damping. |
What are the uses of Aluminium composite board? | Sound proofing panels in cars, boats and signage. |
State the component materials in Concrete. | Cement powder, sand, aggregate particles mixed with water. |
What are the properties of Concrete? | High compression strength, low tensile strength, few surface defects, easy to mould. |
What are the uses of Concrete? | house foundations, driveways and blocks. |
What does Reinforced concrete has in it that Concrete does not, making it more suitable to make buildings out of? | low carbon steel rods (rebar). |
State the component materials of Reinforced Concrete? | Cement powder, sand, and rebar mixed with water. |
What are the properties of Reinforced Concrete? | High compression and tensile strength, consistency across structure, few surface defects, fire resistant. |
What are the uses of Reinforced Concrete? | Buildings, grid floors and bridge piles. |
State the component materials of Fibre Cement. | Cement powder, sand, aggregate particles and polymer or steel fibres mixed with water. |
What are the properties of Fibre Cement? | Lighter in weight than reinforced concrete, hard, tough, good at low temperatures and in freeze/thaw situations. |
What are the uses of Fibre Cement? | Suspended floors, complex geometric shapes and pathways. |
State the component materials of Engineered Wood. | Timber laminates and MF adhesive. |
What are the properties of Engineered Wood? | Good aesthetics, natural alternative to reinforced concretes, more lightweight than concrete alternatives, fire resistant, good structural stability, corrosion proof. |
What are the uses of Engineered Wood? | arches, rafters and bridges. |
