Influence of Content and Arrangement of Reinforcements on Properties of Polyester Laminates

This paper investigates mechanical properties of polyester laminates reinforced with different layers of glass fibres with additives. Testing plates were made by soaking of reinforcements with resin and applying manual air extraction using hand roller. On the basis of results of testing for obtaining tensile, flexural and interlayer strength, modulus of elasticity, impact toughness and content of inorganic matter, it is concluded that mechanical properties of polyester laminates depend not just on “ composition” but on voids which are as inhomogeneities present in boundary of matrix and reinforcements too.
