Sažetak
Polymer composites have been used in industry for more than fifty years, from shipbuilding all the way to aviation and vehicles. Numerous excellent properties of these materials, low costs and simplicity of production have resulted in large expansion of their application area. In the application in aviation industry materials have to be of low density, high strength and rigidity regarding density, as well as of excellent physical properties. The paper presents the procedures and the conclusions regarding the fabrication of laminated hybrid composite plates composed of carbon and glass fibres and the testing of their mechanical properties. In the former case, the central layer of the composite plate is made of glass fibres and the external layers are made of carbon fibres, but in the latter case, the central layer is made of carbon, and the external layers of glass fibres. As result, the impact of laying up of such hybrid polymer composites on
mechanical properties (tensile and flexural properties) has been tested. The paper concludes with a parallel with some materials that are implemented in aviation (aluminium alloys and laminated composite materials with only one type of reinforcement).
