Specifics of the possible applications of polyester laminates considering mechanical properties

This paper examines the possibility of applying polyester laminates with reinforced different layers of glass fibers concearning the mechanical properties. Test plates are made by impregnating reinforcing fibers with resin with the manual extrusion of air bubbles by rollers. Based on the results of strength test (interlayer, tensile and flexural), modulus of elasticity, toughness and share of inorganic matters, it was concluded that the mechanical properties of polyester laminates depend not only on the „composition“, but also cavities presenting themselves as no homogeneity in boundary matrix/reinforcement.
