Question

A glass matrix is reinforced with unidirectional silicon carbide fibers and loaded in longitudinal tension until matrix failure. Determine the minimum fiber volume ratio, so that the composite does not fail catastrophically

Answer 1

Answer:

Vf=0.814

¥-vf=81.41%

Explanation:

Fft(1-Vt)Em=Fmt*v*e

3175(1-v)*69*10³

125*v*400*10³

(4.3815)*(1-vf)=v

V=4.3815/5.3815

Vf=0.814

And vf=81.41%
