Answer:
0.3129
Explanation:
Calculate The minimum fiber volume fraction using the relation below
E = x * E1 + ( 1 - x ) E2 ------ ( 1 )
given that :
E = 83 GPa , x = ?
E1 = 260 GPa , E2 = 2.4 GPA
Insert values back into equation 1
Then ; 80.6 = 257.6 x
∴ x ( volume fraction ) = 80.6 / 257.6 = 0.3129
