The aim of this study is to evaluate the suitability bioplastic bottles for wine packaging. largely packaged in glass bottles, although alternative solutions such as laminate, plastic and bag-in-box packaging are decidedly widespread on market by virtue their ease use low cost, especially so-called entry-level products. However, involving partial or exclusive subject discussion scientific commu...

The mechanical properties of virgin/recycled high-density polyethylene (HDPE) blends over the complete concentration range was thoroughly investigated in this work. In particular, a focus made on long-term via fatigue. Two different mixing methods, namely powder (dry blending) and extrusion (melt blending), were used to determine effect processing conditions tensile fatigue behavior after compr...

Fused deposition molding (FDM) can complete most complex preparation of drug delivery implants to meet the personalized needs patients. However, activity has strict requirements on processing temperature and method filaments, implant also biocompatibility for materials. In this study, a was prepared with good biocompatibility, controlled efficient release using FDM printing administration. Drug...

Thermoplastic polyurethanes (TPUs) bear tunable chemistry offering the possibility to develop a rich palette of physio-mechanical properties, making materials suitable for various fields application. The great variety in TPUs properties comes from choices monomers and reaction conditions. Herein, mechanical developed are tailored, while fine-tuning hard soft segment molar ratio, as well synthes...

Advanced composite materials used in high-tech fields are widely reinforced with carbon fibers. One of the growing application areas for fibers is their composites which to replace metallic automotive parts. This reduces footprint through weight reduction, a strategy pursued globally reduce environmental impacts passenger vehicles. In this study, we assess reinforcement potential recycled polyp...

Abstract BACKGROUND: Craniectomies requiring skull reconstruction are indicated following oncological resection of masses involving the underlying brain and/or skull. Immediate cranioplasties have previously been performed using suboptimal hand-bending or molding techniques ‘‘off – shelf’’ products. Today with computer aided design, customized craniofacial implants become widely available for p...

Life cycle assessment is used to systematically evaluate the environmental impact of underground plastic recharge chambers (RCs) for stormwater management. Using cradle-to-gate life and a functional unit 1 m3 capacity, different RC structure types, manufacturing processes materials are considered. The inventory based on various commercially available RCs, including injection-molded or extruded ...

The rheological behavior of feedstocks used in powder injection molding technology influences strongly on the final properties of the products. Powder loading is one of the important factors that have a great distribution on rheological behaviors. By using the gas atomized spherical 316L stainless steel powder and the binder of 55% paraffin wax+ 40% polyethylen+ 5% stearic acid, four kinds of f...

Rectangular waveguide is one of the earliest types of transmission lines. Rectangular waveguide can be produced by hot extrusion process. In this paper, the hot extrusion process of CuZn5 rectangular waveguide was investigated by Finite Element Method (FEM). In addition, Genetic Algorithm (GA) was used to optimize the die geometry and process conditions to achieve the lowest magnitude of extrus...

In this paper, we studied the effect of different carbon-based nanostructures on electrical and mechanical properties polypropylene (PP) nanocomposites. Multi-walled carbon nanotubes (MWCNT), expanded graphite (EG), two black nanoparticles (CB) have been dispersed at several weight contents in polymer matrix through a melt extrusion process. The produced nanocomposites used to obtain samples fo...
