Information about Composite materials

1. Nanocomposites
➢Nano composites are composites in which at least one of the phases shows
dimensions in the nanometer range (1 nm = 10–9 m)
➢Changes in particle properties below critical size

Opportunities, Materials Research Vol. 12, No.1, 2009

2. Nanocomposites
➢Interactions at phase interfaces become largely improved
➢Enhancement in materials properties
➢Surface area/volume ratio of reinforcement materials is crucial
➢This affects the structure structure–property relationships

3. Nanocomposites
➢Superior properties compared to the constituent materials
➢Ability to tailor properties (mechanical, electrical,thermal, optical,electro
chemical catalytic etc)

5. Nanocomposites
➢High surface to volume ratio
➢Nano partilces, sheets or fibers
➢Interface area is atleast an order of magnitude higher
➢Matrix properties are greatly affeceted at the vicinity of the reinforcement
➢Small amount of nanoscale reinforcement has observable effect

10. Nanocomposites
➢Ceramics have good wear resistance and high thermal and chemical
stability.
➢Ceramic-matrix nanocomposites-significant enhancement on mechanical
properties
➢Incorporation of energy-dissipating components such as whiskers, fibers, platelets
or particles in the ceramic matrix may lead to increased fracture toughness

11. Nanocomposites
➢Crack deflection or bridging
➢Al

12. Nanocomposites
Processing of Nanocomposites
➢Metal matrices employed in MMNC are mainly Al, Mg, Pb, Sn, W
➢CMNC matrix materials include Al
2O
3, SiC, SiN, etc
➢Whole range of polymers, e.g. vinyl polymers, condensation polymers, polyolefins,
speciality polymers (including a variety of biodegradable molecules) are used.

13. Nanocomposites
Reinforcement
➢Synthetic and natural crystalline reinforcements
➢Fe and other metal powders, clay, silica, TiO
2and other metal oxides
➢Clay and layered silicates are the most common
