Question

1.              What are the two main components of FRP ? What does matrix refer to?

3.              Define Fiber Volume Fraction, Vf in a sentence.

4.              An S-Glass FRP material with continuous fibers has a Vf=55%, using the rule of mixtures equation ;

E=VfEf +VmEm where Vm=1-Vf

            Calculate the material elastic modulus, E, given that the approximate elastic modulus of the fibers is 12,000 ksi, and that of the matrix is 600 ksi .

5.              What is the contribution of the matrix to the total E of the FRP in %? Note that you need to use Vf to estimate it. Show your work.

Explanation / Answer

1)

Where the two major components they are fiber and polymer matrix.

Where the matrix role is transfer pack and defense for environmental elements
