6. TYPES OF COMPOSITES
1. Particle reinforced
composites
2. Fibre-reinforced
composites
3. Structural composites

7. PARTICLE-REINFORCED COMPOSITES
Used in particle reinforcing1
CCeramics,glasses(small mineral particles)2
Metal particles(Al and amorphous
material)3
Polymers and carbon blocks4

8. FIBRE- REINFORCED COMPOSITES
• Metals,cerami
cs,glasses or
polymers are
used to made
fibre
reinforced
composites.
• Fibre
increases
themodulus
of the matrix
material.
• It is a type of
advanced
composites
group.
• Indoor
furnitures
• window
glass and
doors
• Fences
This are the
application.

9. STRUCTURAL COMPOSITES
2 Geoetrical design
Constituents1
The properties of structural composites depends on:

10. SOME ADVANTAGE & DISADVANTAGE
OF COMPOSITES
1
2 Lower assembaly cost
3 Weight reduction
4 Nonvisible impact damage
5 Tailorable mechanical properties
Higher material cost
