Ion Ciucă, Dumitru Bolcu, Marius Marinel Stanescu, DINU VERMESAN, RADU PREJBEANU, CRISTIAN CATALIN PETRE5, AURELIANA CARAIANE, SABIN RIZESCU Experimental Research Related to the Mechanical Properties of Composite Materials Reinforced with Woven Polypropylene


Abstract:
In this article we obtained the characteristic curves for polyester and epoxy resins used in the process of making composites, and determined their elastic and resistance properties as well as the characteristic curves on two directions for the epoxy and polyester resin composites, reinforced with woven polypropylene. We established the flow strain and two coefficients from the calculus relation for the plastic potential. We determined the equation of nonlinear dependency between strain and deformation in the plastic field using a fourth degree polynomial relation which indicates the specific elongation and resistance to fracture. Keywords: composite materials, polypropylene fabric, plastic field
