Unidirectional carbon fiber–epoxy composite specimens were produced and three-point bending tests were carried out at spans of 10 and 80 mm. During the tests images were taken using a CCD camera system and the type of damage was studied. The fracture process of unidirectional composite beams were modeled during the 3P bending test considering the beam built up of elementary embedded-fiber layers considered as E-type fiber bundle cells using the formulae developed in the first part of this paper. The fracture processes obtained by measurements were compared to the modeled expected value processes completed with deviation field or confidence interval.
