Opis:
Polyester-glass composites are widely used in many industries, in various types of constructions, including dynamically loaded ones. This article examines the influence of the content of a glass-polyester recycled additive on the strength properties of layered composites. The recyclate was polyester-glass waste, which was pre-crushed and then milled into the appropriate fractions. Manual laminating technology was used to make the materials. The composite materials were made with a waste content of 0%, 10%, 20% and granulations of ≥ 1.2 mm and ≥ 3 mm. Samples for testing were prepared in accordance with the PN-EN ISO 179-1: 2010E standard (Plastics – Charpy Impact Assessment – Part 1: Non-instrumental impact test). Impact tests of the samples were performed using the Charpy method with the Zwick Roell RKP450 swinging hammer. The test results showed that the addition of polyester-glass recyclate, its content %, and its granulation size, have an impact on the composite resistance to loads in dynamic tests.

Opis:
In this article the problem of plastic recycling, and in particular waste polyester-glass, has been described. In brief, the technology for the production of new composite materials by hand, made by the contact method, using the matrix filling in the form of polyester-glass waste coming from worn-out laminates used in the construction of ship hulls. The waste used was a powdered mixture of resin particles, glass fibers, and composite particle agglomerates. A method for producing composite panels with a recyclate content of between 10% and 30% was carried out. The samples were then manufactured according to the requirements of the standard, i.e. PN-EN ISO 527-4_2000P. Samples obtained from the test plates were subjected to a static stretch test, to verify the impact of the integrated wastes on the mechanical properties of the composite. Photographs of the structure of the obtained material have also been presented. These photos showed significant differences in the composition of the resulting composites determined by the amount of waste material used. Analysis of the results indicated that increasing the amount of recyclate reduces the value of the material’s strength limit and also reduces the plasticity of the material. This article has provided an introduction to more comprehensive research on the recycling of plastics.

Opis:
The aim of the research was to determine the effect of polyester-glass recyclate on the deflection of composite samples subjected to three-point bending. The polyester-glass recyclate was obtained from the part of the ship’s hull made of polyester-glass composite, constituting scrap metal. The pieces of scrap were pre-fragmented and then processed into a prepared stand for this purpose. Such a fragmented recycling will be used to make composites with different scrap / recycled content. For this purpose, research materials were made using the vacuum bag method with the percentage of 0%, 10% and 20% recyclate) as well as various granulation (i.e. 1.2 mm and 3.0 mm). The research material consisted of rectangular plates with a thickness corresponding to the thickness of the samples. The samples for testing were made by water cutting. The tests were carried out on a suitably prepared stand, which was made of a universal Zwick Roell testing machine and three-point bending handles and a dial indicator. The spacing of the supports has been determined in accordance with the binding standard for three-point bending. Obtained results from tests, i.e. strain, stress, deflection, deformation allowed analysing the impact of recyclate on bending strength and defining the deflection arrow. Based on the results obtained from three-point bending, it can be concluded that the polyester-glass recycling has an influence on the decrease of strength, stress and deflections of the tested composites.

Opis:
The article presents an overview of modern plastics for use in rail vehicles. The analysis of plastics and composites in the constructional aspect was analyzed. The trends in the development of polymer materials, technologies and constructions used in the manufacture of vehicles, on the one hand, are determined by the technical and economic requirements of industry and, on the other, by the continued emphasis on reducing fuel consumption and CO2 emissions. Further development will be subject to pre-impregnation techniques, particularly in the form of different types of reinforcement. Full use of the advantages of reinforced polymer materials in vehicle production will only be achieved when further optimization of the resin properties and development of automation will result in the widespread use of composite components in series production. Observing the trends and pace of development, it is possible to predict that there are still restrictions on the use of polymeric materials in the transport sector, such as relatively high prices, technological constraints and the hindering automation of large-scale production. Modern construction and material solutions, in particular those using reinforced plastics, are primarily designed to reduce vehicle weight and have better noise and vibration damping properties. Rail vehicles are becoming more environmentally friendly at the time and travel comfort is higher.
