Abstract In industrial applications, the potential of basalt fibre-reinforced polymer (BFRP) composite pipes as a compelling alternative to glass and carbon is recognized. Their high recyclability makes them viable option for aerospace, marine, automotive applications. this study, comparison made between mechanical properties virgin basalt–epoxy graphene-modified counterparts. To conduct experiments, pipe section specimens were prepared using flex grinding machine. Graphene nanoplatelets...
This article deals with the influence of electron-beam radiation on micro-mechanical, thermo-mechanical, and structural properties selected polymers. In search for desired improvement polymers, it is possible to use, inter alia, one particular modification-Namely, crosslinking-Which a process during which macromolecular chains start connect each other and, thus, create spatial network in structure. course treatment ionizing radiation, two actions can occur: crosslinking scission...
Abstract This article aimed to compare various mechanical properties of epoxy/graphene and epoxy/halloysite nanocomposites. Graphene nanoplatelets (GnPs) halloysite nanotubes (HNTs) were used as fillers at different concentrations. The studied dispersed in the epoxy resin matrices. Elastic–plastic behavior modulation was observed utilizing fillers’ nanoparticles carboxyl-terminated butadiene–acrylonitrile copolymer rubber-modified resin. hypothesis possible preceding inter-particle gliding...
Cross-linking is a process in which polymer chains are associated through chemical bonds. The cross-linking level can be adjusted by the irradiation dosage and often means of booster. additional influences surface nanoand micro layers way comparable to metals during thermal chemical-thermal treatments. aim this paper study effect ionizing radiation with different doses (33, 66 99 kGy), on micro-mechanical properties polyethylene (HDPE) compare these results those non-irradiated samples....
The presented article deals with the research of micro-mechanical properties in surface layer modified Polyamide 66 filled by 30% glass fibers. These were measured Depth Sensing Indentation - DSI method on samples which non-irradiated and irradiated different doses β radiation. Radiation used 0, 15, 30 45 kGy for 6% cross-linking agent (triallyl isocyanurate). Individual radiation caused structural changes have a significant effect final polyamide tested. highest values reached at dose kGy,...
This study investigated the mechanical, thermal, and morphological properties of acrylonitrile butadiene styrene (ABS)-based nanocomposites reinforced with different types concentrations nanofillers. The uniaxial tensile testing results indicated that Young's modulus (E) generally decreased increasing filler content, except at 0.500 w.% concentration, where a slight increase in stiffness was observed. A statistically significant interaction between sample type concentration identified (p =...
This publication deals with the study of mechanical properties injection-molded polypropylene parts depending on process parameters and distance from gate location in which were investigated. Due to fact that are not same at all locations, this research was designed investigate inhomogeneity along length product. The is affected by various influences, including sprue mouth, melt mold temperature, injection pressure, crystal structure, others. It demonstrated uniform over entire injected...
Abstract Two different nanosized mineral fillers (nano calcium carbonate and nanoclay) were used in the high density poly(ethylene) (HDPE) composites pilot plant production. Structural mechanical properties of prepared examined this study. The homogenous filler distribution was confirmed tested samples by scanning electron microscopy, transmission energy dispersive spectroscopy analyses. fillers’ fortifying effect on polymer composites’ performance as indicated increased elastic modulus...
This study investigates the challenges and potential of conventional injection molding for producing thick-walled optical components. The research primarily focuses on optimizing process parameters mold design to enhance product quality. methods include software simulations experimental validation using polycarbonate test samples (optical lenses). Significant such as melt temperature, pressure, packing pressure were varied assess their impact geometric accuracy visual properties. results...
Abstract This paper was focused on application of the perlite mineral as filler for polymer nanocomposites in technical applications. A strong effect nano-filler high-density poly(ethylene) (HDPE) composites’ mechanical and thermal properties found. Also found an increase Young’s modulus elasticity with increasing concentration. Increased stiffness from tensile testing confirmed by nondestructive vibrator well. based displacement transmissibility measurements means forced oscillation...
Polypropylene (PP) belongs among the most important commodity plastics due to its widespread application. The color of PP products can be achieved by addition pigments, which dramatically affect material characteristics. To maintain product consistency (dimensional, mechanical, and optical), knowledge these implications is great importance. This study investigates effect transparent/opaque green masterbatches (MBs) their concentration on physico-mechanical optical properties produced...
The aim of this research paper is to study the effect particle size recycled polymeric material mechanical tensile properties. During grinding particles are formed which have a different size, shape and surface, from larger pieces dust particles. processing these melt at rates depending on their size. For example they can cause degradation or lack homogeneity. Several mixtures were prepared that had differed after crushing. always same as original material. studied was Polycarbonate. Testing...

As can be seen from results, different influenced hardness quenching tempering. Lower shorter led insufficient homogenization austenite...
ABSTRACT A 2-year national genomic screening in the Czech Republic identified a notable prevalence of New Delhi metallo-β-lactamase 5 (NDM-5)-producing Escherichia coli sequence type 38 (ST38) city Brno. Forty-two ST38 E. isolates harbored bla NDM-5 gene on chromosome. Virulence factors confirmed persistence these through biofilm formation. Single Nucleotide Polymorphisms (SNPs)-based phylogeny and CRISPR assay typing showed minimal variations, implying clonally driven outbreak. Results...
At the present time bonding has spread into almost all sectors of practice and it would be very difficult to find an industry in which there is no need use this technology joining a wide range materials. In comparison with conventional methods (riveting, welding screwing) provides new combination options allows obtaining special shapes properties cannot created by coupling. For formation quality bonded joint important that adhesive surface well wetting. Wettability characterized contact...
