Opis:: The article examines the effect of the change in the speed of deformation on the mechanical properties of AW 6060 alloy specimens, characterized by high mechanical strength, which is a material used in the shipbuilding industry. The theoretical basis for the influence of load speed on the mechanical properties of materials is presented. Static and dynamic tensile test was conducted on a universal testing machine. Dynamic stretching was performed on samples at 10–1 s–1 – 102 s–1. Done charts and tables showing results. Calculated in accordance with DIN EN ISO 6892-1 2010P total elongation and contraction of the sample. Comparison of the results of the study with the current knowledge of the subject. Material studies have shown that increasing the deformation rate results in an increase in the yield point and tensile strength. On the basis of calculations of the narrowing and elongation of the total sample, the material can be strengthened. The rate of deformation of the materials is favourable for their strengthening by increasing the limit of tensile strength. Given that most of the design is subject to dynamic loads and the aluminum alloy AW 6060 finds extensive use in shipbuilding and beyond, these are satisfactory results.

Opis:: Glass fibre reinforced composites are used in many branches of industry. Polyester-glass laminates serve as structural material in shipbuilding (e.g. hulls of units, superstructures), in railways, automotive (e.g. elements of car bodies and interior fittings, roofs of wagons, cisterns) or aviation (e.g. aircraft fuselages, fuel tanks, completion beaks and ballasts). Factors affecting the increase of their use include low specific gravity, optimal strength properties, corrosion resistance. This is associated with a large amount of post-production and post-use waste. The recycling problem of these materials remains unresolved. The article presents the technology of processing polyester-glass waste in order to obtain a recycle with a specific granulation. The selected technology for the production of layered composites with reinforcement in the form of recycle is described. For testing, granulation was selected for 1.2 and 3 mm, as well as content: 0%, 10%, 20% and 30%. Using the water-cutting method, samples were prepared according to the standard static tensile test for plastics. The tests were carried out using a universal testing machine as well as an extensometer for samples with granulation of 1.2 mm and 3 mm, as well as the selected recycled percentage. Obtained results of the research indicated that granulation as well as content affects the strength properties of composites. As the granulation increases, at the same content, the material gains less deformation. The increase in the amount of the recycle reduces the strength properties of the material, and also due to the decrease in the deformation value - the material becomes brittle.

Tytuł:: Resistance to aging research in sea water composites with the polyester-glass recyclate

Opis:: Composites are materials used for various types of constructions in the automotive industry, aviation, and shipbuilding. Due to the wide use of these materials, there is a problem with their recycling. Such material requires appropriate processing technology, which has been developed to obtain a recyclate with a specific granulation. The use of hand laminating technology made composites with the addition of polyester and glass recyclate with granulation of 1.2, as well as content: 0%, 20%, 30%. These types of materials are exposed to various types of atmospheric factors that affect their durability. Aging is defined as changes in the composite when exposed to atmospheric conditions, such as sunlight, temperature, thermal cycles, water in various forms and wind. This article uses recycled polyester and glass composites to investigate the effect of aging in seawater on their strength properties. These tests can be used to pre-assess the applicability of newly developed materials as construction or protective coatings. They were carried out on a specially prepared station for accelerated tests, with elevated temperature (35ºCC), as well as brine spray imitating sea atmosphere. The method is used to accelerate the aging processes occurring in composite materials. Samples were subjected to cycles of 5, 30 and 60 days respectively. Samples were weighed and measured before and after each cycle. In order to investigate the effect of aging on strength properties, the composites underwent a static tensile test in accordance with the standard for plastics. Studies have shown that as a result of the aging process, the strength properties decrease slightly, which affects the favourable assessment of these materials as constructional.
