Tribological and Mechanical Properties of Polyester Laminates

Tribological and mechanical properties and damages of fibre reinforced polyester laminates have been examined. They depend upon the number of reinforcing layers, their layout and thickness. Different layers of glass fibres (“ mat” and “ roving” ), as well as matrix of polyester resin with additives and calcite, have been used as reinforcing links. It can be concluded that mechanical properties of polyester laminates depend not only on the composition but also on the homogeneity of the structure, i.e. the presence of larger number of cavities and holes, as indicators of non-homogeneity. It has been determined that composites with less voids have better properties. The best correlation is noticed between the flexural strength and wear resistance.
