Abstract
Unidirectional composites reinforced with long brittle fibers may suffer from fiber breaks. Fiber stress in broken fibers changes from zero to that of intact fibers as axial distance increases from each fiber break. The distance for such a transient change of fiber stress is called the stress recovery, or transfer, length and is important for evaluating the longitudinal tensile strength of composites.
