For a fiber-reinforced composite, the efficiency of reinforcement η is dependent on fiber length L according to:
η = (L – 2x)/L
where x represents the length of the fiber at each end that does not contribute to the load transfer.
a) Using MATLAB, plot η versus L (up to L = 40 mm) assuming that x = 0.75 mm.
b) What length is required for a 0.80 efficiency of reinforcement?
