Investigation on the lifetime of threads. S-N curves of different manufacturing processes.

The paper investigates the combination of experimental data with a thermal model and parameter estimations to determine the heat transfer coefficients of a specific production step of wood-based panel manufacturing.

Replacing part of the content of the polycaprolactone matrix with a biopolymer is one of the possibilities of using hydroxyethyl cellulose as a filler. A compatibilizer - a copolymer of ethylene with acrylic acid was used to improve interfacial adhesion, which affects the morphology and mechanical properties of thermoplastic blends.

Waste tire pyrolysis carbon black was used as a filler to replace conventional carbon blacks in the polymer matrix with aim to reduce costs and waste from waste tire pyrolysis. The reduction fraction of carbon black from waste tire pyrolysis is necessary to improve the reinforcement of the polymer matrix.

The framework for research in field of materials’ properties degradation is proposed. The application is in the research of additive manufactured spare parts aboard ships.

The paper presents a method to determine the residence time distribution of single-screw rubber extruder using experimental data and a digital image processing method, in order to predict the residence time distribution within a machine learning approach.

The presented study evaluated the effects of intensive plastic deformation, realized by rotary swaging under hot conditions, on the deformation behavior of a WNiCo tungsten heavy alloy. The sintered microstructures exhibited a more or less homogeneous distribution of tungsten agglomerates and nickel-cobalt matrix.

Galfan coating prepared by the hot dipping process reduced the ultimate tensile strength and yield strength of the cold rolled CRS 1018 steel, whereas the elongation was significantly increased. The results of the nano indentation testing implied that the dislocation density of the coated steel might be lower than that of the uncoated specimen, which led to the change of mechanical properties.

The aim is to access the potential for replacing glass fibers with natural fibers in the manufacturing of printed circuit boards. Finite element method was used to evaluate the influence of the main structural parameters on their thermomechanical properties. The objective is to predict and quantify the warpage, following the temperature profiles that are important to the soldering process.

The effects of alloying, cold forging, and heat treatment on hardness, strength, and toughness were studied. Combined thermomechanical processing showed notable improvements, highlighting the potential of optimized copper-chromium-phosphorus alloys for enhanced mechanical performance.

This study examines the surface modification of polyvinyl chloride, polyethylene terephthalate, and PP films via diffuse plasma, highlighting the backside treatment effect-changes in areas not directly exposed. Plasma activation altered surface energy, wettability, and adhesion. Contact angle analysis confirmed improved wettability. Findings are key for precise surface engineering.

The research aimed to synthesize and determine the properties of the geopolymer materials from industrial byproducts. The research confirms the applicability of the process of geopolymerization to stabilize slags and ashes from municipal waste incineration plants. The material's potential can be useful for some basic civil engineering applications.
