Composite Materials

 
8.4   Composite Materials 
 
Introduction to Composite Materials
  • A composite material is a material made from combining two or more non-homogeneous substances. 
  • These non-homogeneous substances are the matrix substance and the strengthening substance. 
  • The matrix substance binds the strengthening substance together. 
 
The image is an infographic titled ‘COMPOSITE’ with a light bulb icon in the center. Surrounding the light bulb are five labeled sections connected by arrows, indicating a cycle. The sections are: 1. Reinforced concrete 2. Fibre glass 3. Fibre optics 4. Superconductor 5. Photochromic glass The Pandai logo is in the top left corner. The design uses blue and red colors for text and arrows

Comparison and Difference in Properties of Composite Materials and Their Original Components
Comparison in Properties of Reinforced Concrete with its Original Components
  • Concrete can withstand high compression forces but will break if subjected to high stretching forces.
  • Combination of concrete and steel bars or wire mesh can increase the ability of the concrete to withstand compression forces.
Comparison in Properties of Fibre Glass with its Original Components
  • Plastic matrix consists of plastic that is weak, soft and easily burned.
  • The properties of plastic are reinforced by adding glass fibres.
Comparison in Properties of Optical Fibre with its Original Components
  • Optical fibre has high compression strength although the original component that is glass fibre, is brittle.
Comparison in Properties of Photochromic Glass with its Original Components
  • Glass is transparent and does not absorb UV rays.
  • Silver halide salt crystals such as silver chloride, AgCl is transparent to visible light and absorbs UV rays at the same time.
Comparison in Properties of Superconductor with its Original Component
  • Superconductors can conduct electrical current without any resistance at very low temperature whereas its original components cannot..
