  • The use of fiber reinforced plastics has increased in the last decades due to their unique properties.Advantages of their use are related with low weight, high strength and stiffness. Drilling of composite plates canbe carried out in conventional machinery with some adaptations. However, the presence of typical defects likedelamination can affect mechanical properties of produced parts. In this paper delamination influence in bearingstress of drilled hybrid carbon+glass/epoxy quasi-isotropic plates is studied by using image processing andanalysis techniques. Results from bearing test show that damage minimization is an important mean to improvemechanical properties of the joint area of the plate. The appropriateness of the image processing and analysistechniques used in the measurement of the damaged area is demonstrated.
