Opis:
The attractive characteristics of polyester-glass composites have led to their use in many industries, but using them as structural elements requires knowing their mechanical properties. This paper presents processing methods of polyester and glass scrap and their use in the production of new composites. This scrap, called the recyclate, was pre-crushed, ground, and then passed through sieves to obtain the desired fractions. Composite materials with added recyclate were made by hand lamination. Composites were made and then used to conduct appropriate tests to determine the degree of cure of the resin, and to determine the effect of the polyester-glass recyclate content on the hardness of composites. For this purpose, rectangular panels with a thickness of g = 8 mm were produced by manual lamination. Each plate contained 0% glass mat, 10% resin, and 20% recyclate with granulation ≤ 1.2 mm and ≤ 3 mm. Then, test samples were formed from each plate. Hardness measurements were performed using the ball-pressing method. In addition, structural studies were carried out to determine the correlation between the structural and mechanical properties of the discussed materials. The obtained test results showed that the recyclate content and its granulation clearly affected the mechanical properties of the tested composite materials.

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.
