چکیده مقاله
The cracks by intralaminar decohesion in composite materials appear a little ahead of the delamination front under the action of triaxial stresses before any decohesion at the interfaces between layers The actual phenomenon of delamination is caused by previous damaging of the resin ahead of the front resulting first in the formation of intralaminar cracks The microscopic mechanisms involve numerous changes of planes formation during delamination, so that delamination cannot he considered, in any case, as a simple decohesion between two adjacent layers Analysis of damaging mechanisms supported by scanning electron microscope SEM observations gave useful information about the conception and design of long fiber reinforced composite materials In this paper after a synthesis on the mechanisms of fracture of composite materials by delamination which were proved by SEM photographs, suggestions have been given for realization of these materials
