Comparison between domestic composite supports of outdoor lighting
This article examines domestically produced supports made of composite materials. In the modern world the use of composite polymeric materials is distributed due to their advantages over other kinds of materials. Nowadays composites are being actively used as material for outdoor lighting supports which are assembled along roads and railways, on private property and in the facilities designed for recreation and sports. In this regard, there are many companies on the domestic market which are ready to offer production of such supports of outdoor lighting. Since development and assemblage of such supports is indeed a fast-moving sector, there are a lot of firms on domestic market which are ready to offer their services. The study builds on the method of comparison of products offered by producers by the following aspects: materials, winding technique, basic physico-mechanical properties, the useful life and cost. All three companies use the same fiber composite, which is fiberglass, as a reinforcing fiber. However, the companies choose different binding agent and method for winding. Therefore, the considered supports have different physico-mechanical properties, the useful life and cost. The results of the study show us that serial composite supports, manufactured by the three considered companies, have different interesting engineering solutions which are being successfully implemented on objects under construction in different climate zones of Russian Federation. Every support has its advantages and disadvantages. The results are of high scientific importance. More and more ways of engineering supports of outdoor lighting are being figured out at present in order to increase their strength and useful life and improve resilience against environmental conditions.
