Sagot :
Answer:
Option D
Explanation:
A composite material is made up of two material which have different properties (chemically or physically). The two materials are mixed in such a way that it improves the properties of both the materials (the one in the matrix and the other in the filler) thereby enhancing the overall strength and stiffness of the matrix.
Hence, option D is correct
A correct option is an option (c)
Composite materials:
The main advantage of the composite is there higher strength as compared to the matrix.
The strength is very low as compared to the resultant composite and the fiber.
The resultant strength can be calculated in two direction
The longitudinal way is,
[tex]E=V_mE_m+V_fE_f...(1)[/tex]
The transversal way is,
[tex]\frac{1}{E}=\frac{V_m}{E_m}+\frac{V_f}{E_f} ...(2)[/tex]
From equations (1) and (2) we get,
[tex]E_m < E < E_f[/tex]
So, mode with strong fibers embedded in a weaker and softer matrix to obtain strength better than the strength of the matrix.
