Glass fibers with a diameter 50 μm are introduced into a 6,6 nylon matrix. Determine the critical fiber length at which the fibers behave as if they are continuous. The strength of the bond between the fibers and matrix is 10 MPa. The relevant materials properties are as follows:
Eglass = 72 GPa, Enylon = 2.75 GPa,
TSglass = 3.4 GPa, and TSnylon = 827 MPa.
