Answer #1

Here the given elastic modules for fibre and matrix are 74Gpa

And 2.4Gpa

So using the formula Ec = fEf + (1-f)Em for longitudinal losing we get

Young's modulus = 31.04 Gpa for composite or 31.04*10^9 pa

And for traverse Ec = (F/Ef - (1-f)/Em)-1

We get Young's modulus = 3.91Gpa for composite or 3.91 *10^9 pa
