The design process is mostly connected with a proper selection of construction materials. Newly designed UAVs must undergo assessment in terms of performed tasks, range or fuel consumption. A significant influence upon the selection of materials, which are long lasting and resistant to damage, is exerted by the conditions of work of Unmanned Aerial Vehicles. They mainly execute their tasks at high altitudes with high speeds, where temperature and pressure differences may extensively damage not only the airframe skin, but also the equipment and the propulsion system itself. The aim of this study is to present the characteristics of materials currently used as well as their assessment in employed construction elements of UAVs. Polymer composites are superior to Al and Ti alloys, steel within the parameters of tensile strength and stiffness. As for the density gradient, polymer carbon fibre composites exceed glass fibre composites, also under cyclically variable loads. Glass fibre composites during tensile testing show higher values and a higher capability of absorbing energy under static and dynamic forces. Polymer matrix composites, reinforced with Kevlar, are less stiff than carbon-fibre composites, due to lower values of elasticity modulus, however they demonstrate higher impact load. Strength tests provide valuable data concerning the properties of a given material, such as tensile modulus E [MPa], tensile strength UTS [MPa], or resistance to high temperatures. It must be noted that these properties significantly affect the functioning of the airframe and its components.
