This study investigates the physical and mechanical properties of biodegradable composites based on PLA/PHBV blends modified with different content of nanocrystalline cellulose (NCC) of 5, 10, and 15 wt.%. Density measurements reveal that the density of the composite increases with increasing NCC content. Water absorption tests demonstrate a gradua...

Featured Application Building materials for products with lower carbon footprints and increased mechanical properties. Abstract This article’s aim is to analyze physical, mechanical, and fracture properties as well as the thermal investigation of geopolymer composites reinforced with flax, glass fiber, and also the hybrid combination of fibers. Tw...

This study examined the impact of hybridization on the mechanical properties of glass–epoxy laminates by incorporating metal oxides and graphite particles into the resin matrix. Basic mechanical tests were conducted, followed by accelerated thermal aging tests. Results showed an increase in bending strength ranging from 12% to almost 30% depending...

This study examines the relationship between the size of copper particles and the properties of epoxy resin. Epoxy resin is a type of thermosetting resin commonly used as a matrix in polymer matrix composite materials reinforced with glass or carbon fibers. As part of this study, three microscale and two nanoscale composite samples modified with co...

The discrete element method (DEM) is a widely accepted method used in simulations of the powder sintering process, where the real object is replaced by a set of particles representing elastic–plastic material. Recently, this method has also been used to model solid materials. In this work, we present a local constitutive model for the determination...

The main objective of the article is to develop the concept of flock fragmentation and the averaging method for the application of electrocoagulation in the process of treating wastewater from coke ovens. The designed solution was part of an innovative system for the coke oven wastewater treatment process. The system is dedicated to removing the ha...

Biocomposites were produced using biobased polyamide (Bio-PA) and two different types of fibers (aramid and basalt). The impact of artificial and mineral fibers on the mechanical properties was assessed in detail, as well as their effects on hybridization. Improvements in mechanical properties were observed following introduction of fibers into the...

The work assumed the possibility of the introduction natural fibers as a hybrid reinforcement of bio-polyethylene composites. Coconut fibers, basalt fibers and wood flour were used in different combination as a hybrid merger. Mechanical tests were conducted. An increase in the mechanical properties was shown as an effect of the introduction of the...

The paper describes the influence of the friction stir welding travel speed on the mechanical properties of the butt joints of copper plates. The results of static and fatigue tests of the base material (Cu-ETP R220) and welded specimens produced at various travel speeds were compared, considering a loading applied both parallel and perpendicularly...

Present work deals with numerical modeling of the material which contain the joint made by using the friction stir welding (FSW) technology. The consider material has a heterogeneous microstructure which determined its global response to the applied load. The thermodynamically consistent elastic-plastic model was introduced, additionally took the a...

Nowadays aluminum and its alloys are very common for various applications, particularly in automotive, aerospace, and ship industries. This is because of their low density, high strength and good corrosion performance. However, due to high thermal and electrical conduction, conventional fusion or resistance welding of aluminium alloys encounters ma...

Friction stir processing (FSP) is a metalworking technology based on the same basic principles as friction stir welding (FSW). Us- ing a stiff tool, FSP can be applied for the bulk or superficial processing of metallic materials. The process could be also applied for local modification of the microstructure for specific property improvement. Moreov...

The thermal modeling of the Friction Stir Welding process allows for better recognition and understanding of phenomena occurring during the joining process of different materials. It is of particular importance considering possibilities of process technology parameters optimization and the mechanical properties of the joint. This work demonstrates...

Praca dotyczy numerycznego modelowania rozkładu temperatury towarzyszącej procesowi zgrzewania tarciowego z mieszaniem materiału zgrzeiny (ang. Friction Stir Welding). Rozważony został obrotowo symetryczny problem opisany równaniem typu Fouriera z wewnętrznym źródłem ciepła. W celu rozwiązania problemu początkowo-brzegowego zastosowany został waria...
