The composite industry looks toward a new material system (resins) based on thermoplastic polymers for the vacuum infusion process, similar to the infusion process using thermosetting polymers. A large number of thermoplastics are available in the market with a variety of properties suitable for different engineering applications, and few of those are available in a not yet polymerised form sui...

A textured dielectric substrate for a broadband miniature antenna was fabricated using a thermoplastic green machining. This substrate comprised of three steps with optimized distribution of a dielectric ceramic (Bi–Ba–Nd–Titania; BBNT) and an epoxy. At first, a thermoplastic compound, consisting of BBNT particles and thermoplastic binders, was machined precisely using a mini-computer numeric c...

The working principle of a nano-crystalline dye sensitized solar cell (nc-DSC) of the Grätzel type depends on a working cycle consisting of dye excitation, electron injection into titanium dioxide and fast reduction of the oxidized dye by a redox couple. Continuous stability testing at Solaronix on glass/glass thermoplastic sealed nc-DSC devices, revealed that no significant degradation of the ...

DeVoe Department of Mechanical Engineering Portable and cost-effective medical diagnostic technologies that require minimal external infrastructure for their operation are highly desirable for on-field milita...

Abstract In order to meet the high demands on tolerances and surface qualities, for example in automotive lighting applications, a hybrid part composed of light metal (aluminium) an amorphous thermoplastic (polycarbonate) could be alternative established mono‐materials used today. Due lack adhesion promoter systems joining this specific material combination, micro‐form‐fitted connection by crea...

The main objective of the presented scientific article is to define mechanical properties polypropylene homopolymer with a prescribed percentage ratio recycled granulate. chosen material intended for injection molding and especially production products made by additive technologies. Experimental verification was realized testing samples produced various concentrations material. underwent tests ...

Sugar beet pulp (SBP) is the raffinate of sugar extraction. Composed of empty vegetal cells, three quarters of it consist of polysaccharides. As it is cheap and produced in great quantities SBP is a potential raw material for industrial applications other than cattle feeding. Twin-screw extrusion modified its structure and destructuring level depended on the specific mechanical energy provided ...

Thermoplastic elastomers (TPEs) are provided with many properties of elastomeric or rubbery materials, but can be processed with the thermoplastic processing methods; they are one of the fastest growing polymers materials which combine the elastic and mechanical properties of crosslinked rubbers with the melt processability of thermoplastics. In addition, TPEs find a lot of applications in auto...

The aim of this work was to develop cassava starch biocomposites with varius concentrations grape skin (Gr) and acerola (Ac) residues (0.1, 1.0, 5.0 10.0 wt%) using extrusion injection molding processes. Grape residue had the highest concentration total monomeric anthocyanin (ANC) Ac phenolic content (TPC) sugars. fruit thermal degradation onset temperatures above processing temperature profile...
