Testing of the mechanical properties of polyester laminates

Polyester laminates are the latest generation materials that are used in various industries. To obtain desired properties such as elasticity, impact strength, wear resistance, bending strength, chemical stability, waterproofness, self-smoothing, etc., it is necessary to combine a range of different chemical components. 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.
