Abstract


Abstract: This study is a part of a work in progress on the mechanical behavior of laminate in various modified epoxy matrices. we begin with a laminate six folds with fiberglass taffeta, and epoxy matrix cross linked by aliphatic Amine called MEDAPOXY STR, this resin isthe report weight of 0,67%. The treatment of the results shows that thein the form of a kit of two elements ,a monomer and a hardener with reticulation of monomer by this Amine is incomplete what provokes a plastic domain on the mechanical behavior of the matrix, concerning composites made from these elements, the results show that the elastic domain is dependent on the elasticity of fibers used and not on thematrix. The control by ultrasound can be considered as another way to measure and follow-up of the parameters elasticity of the elaborate laminate.
