Composites and Masonry

Question 1

What four characteristics do composites have?

Answer 1

– Combination of materials which differ
in composition or form
– Remain bonded together
– Retain their identities and properties.
– Act in concert to provide improved
specific or synergistic characteristics not
obtainable by any of the original
components acting alone

Question 2

Two phases in composites?

Answer 2

• Matrix phase

- Dispersion Phase

Question 3

What is the matrix phase?

Answer 3

It is the continuous material constituent which encloses the composite and gives it its bulk form

Matrix phase may be metal , ceramic or polymer

Question 4

What is the Dispersion Phase?

Answer 4

It is the structure constituents, which determines the internal structure of composite.

Dispersion phase is connected to matrix phase by bonding

Question 5

What is toughness?

Answer 5

The ability of a material to absorb energy and deform without fracturing
