“…The course is plotted as a function of time or temperature. The material is placed on metal pads, which reduce the thermal gradient to a minimum [24,25]. The condition was to achieve high heating values (in tens of K.min -1 , • C.min -1 ) in the analysis, thus ensuring a high resolution of heating and, therefore, the obtained temperature scale [26].…”

Taking climate and geopolitical issues into account, we must shift our thinking towards “eco” and focus on renewable energy. The accessible solar energy represents 400 times the amount of consumption, while its potential represents 10,000 times the amount of demand. The paper aims to analyze recycled, customized polyvinyl butyral (PVB) with high purity (more than 98%) concerning its physicochemical and mechanical properties and its possible applicability in the photovoltaic industry as an encapsulating material. The detailed investigation on polyvinyl butyral starting from characterizations, homogenization, and moulding process to tensile tests and used exposure testing in laboratory apparatus are performed. Samples of recycled polyvinyl butyral were exposed to ultraviolet (UV) radiation of the value 0.76 W.m–2.nm–1 at 340 nm, water spray, drying at 50 °C and condensation for 320 h when the radiation was turned off. The results obtained were more controlled in a laboratory environment than those found in external, uncontrolled environments. These conditions subsequently accelerate any degradation of polyvinyl butyral as a material and subsequent degradation of the final product.

Geopolymers are materials prepared from alkaline-activated cement without a calcium constituent. They are synthetic materials based on aluminosilicates. The main advantage of these environmentally friendly materials is that they save mineral resources and due to being free of calcium constituents, and only a small amount of CO2 emissions are released into the environment. The circular economy model of sustainable development of new composite materials will ensure the competitiveness of industries, their stable economic growth, and a healthy environment. This paper aims to investigate geopolymer composite materials that were reinforced with a mixture of glass powder from recycled windscreens. The glass 100% circulates in the closed material cycle and can be used again in the manufacturing process without any loss of quality. We are focused on verification of readability of selected automatic identification technology and their usability directly in the manufacturing process of geopolymer composite materials.

“…Fibre-reinforced composite structures have become highly competitive engineering materials in recent years, and they have gradually replaced conventional metallic and other polymeric materials in many important industries [3]. Epoxy-based composite materials are used in load-bearing structures such as aircraft, military vehicles, ships, structures and offshore structures due to their advantageous mechanical, physicochemical properties and high strength-to-weight ratio [5]. Improving fire resistance has been given top priority to increase market penetration and given the current strict aviation legislation and other safety measures [5], [6].…”

“…Their specific strength and modulus of elasticity are significantly lower than those of carbon fibres. In combination with the positive coefficient of expansion of the matrix resin, highly dimensionally stable components can be produced [3], [5]. Compared to carbon fibre reinforced plastics, the compressive strength of aramid fibre composites is significantly lower.…”

In general, epoxy resins are known for their excellent adhesion, chemical and thermal resistance, unique mechanical properties and excellent electrical insulators. The various fibres are incorporated into epoxy resin matrix materials. With the prepared samples, the fibre tests are passed. The results of the investigation are also taken into account due to the strength of the connection between the fibre and the matrix. The aim of our research is the preparation and subsequent testing of epoxy-based composite materials during their manufacturing operations, specifically by casting technology. The properties of fibre-reinforced composites depend significantly on the choice of fibre and matrix, and how they are combined, the fibre-matrix ratio, the fibre length, its orientation, the thickness of the composite and the presence of a bonding agent to improve fibrematrix bonding.
