Question

The smallest volume part of a composite is called
Select one:
a. Reinforcement Material
b. Matrix Material
c. Interface
d. Concrete
​

Answer 1

Answer:

a

Explanation:

Answer 2

Option (a) is the correct answer.

The smallest volume part of a composite is called Reinforcement Material.

Explanation for Correct answer:

Reinforcement materials

• Reinforcement materials add rigidity and greatly impede crack propagation to the structure.
• They enforce the mechanical properties of the matrix.
• They are harder, stronger, and stiffer than the matrix.
• E-glass. is the most common type of composite reinforcement.
• E-glass has the lowest modulus, but it  has relatively good tensile strength.
• The most inexpensive glass fiber is  E-glass.

Explanation for Incorrect answer:

b. Matrix Material - Metal matrix composites are composite materials that contain at least two constituent parts – a metal and another material.

c. Interface-It is the region that is formed when two phases or systems are in contact with each other through which the intensive properties of one phase transfer to the other.

d. Concrete -The ingredients which make up the concrete mix are: cement, fine aggregate, coarse aggregate, water, chemical admixtures, and mineral admixtures.​
