For a fiber-reinforced composite, the efficiency of reinforcement η is dependent on fiber length l according to where x represents the length of the fiber at each end that does not contribute to the load transfer. what length is required for a 0.63 efficiency of reinforcement, assuming that x is 0.74 mm?

Length required will be 0.004 m

Explanation:

We have given efficiency of the reinforcement

We have to find the length required for the reinforcement

x is given x = 0.74 mm =

x represent length of the fiber at each end

We know that efficiency is given by

So

l= 0.004 m
