Nonlinear electric conductance of reinforced insulation can homogenize field distribution and suppress local distortion inside high-voltage direct current cable accessories. To achieve a significant nonlinear in ethylene–propylene–diene misch–polymere (EPDM) used for accessories, the inorganic micron crystal powder calcium copper titanate (CCTO) is synthesized by sol–gel method, which filled in...

Thermoplastic elastomers (TPEs), based in PP (Polypropylene) / EPDM (Ethylene Propylene Diene Monomer) have as purpose improving resistance and impact, aiming to a more comprehensive use automotive market, among edifications, construction packaging sectors, due their recyclability properties. is commodity, with high melting point, mechanical low density, posing balance between physical properti...

PURPOSE Aortic Customize is a new concept for endovascular aortic aneurysm repair in which a non polymerized elastomer is injected to fill the aneurysm sac around a balloon catheter. The aim of this in vitro study was to investigate the extent of aneurysm wall stress reduction by the presence of a noncompliant elastomer cuff. METHODS A thin-walled latex aneurysm (inner radius sac 18 mm, inner...

STATEMENT OF PROBLEM The clinical life of a maxillofacial prosthesis averages about 6 months, before it needs to be refabricated. Degradation of the color and physical properties of the prosthesis are the principle reasons for replacement. PURPOSE This second part of a 3-part in vitro investigation evaluated the change in physical properties of popular colorant-elastomer combinations as a res...

Stimuli responsive hydrogels may be promising materials for shape transforming structures due to their ability to deform significantly in response to an environmental stimulus without the need for external power. It is well-known that by laminating swelling hydrogels and non-swelling flexible materials, such as inert elastomers, bending actuation can be achieved. In this work, we report an impr...

It is well known that elastic instabilities induce pattern transformations when a soft cellular structure is compressed beyond critical limits. The nonlinear phenomena of pattern transformations make them a prime candidate for controlling macroscopic or microscopic deformation and auxetic properties of the material. In this present work, the novel mechanical properties of soft cellular structur...

Current materials used for maxillofacial prostheses are far from ideal and there is a need for novel improved materials which mimic as close as possible the natural behavior of facial soft tissues. This study aimed to evaluate the effect of adding different concentrations of surface treated silicon dioxide nanoparticles (SiO2) on clinically important mechanical properties of a maxillofacial sil...

Thin metal films deposited on elastomeric substrates can remain electrically conducting at tensile strains up to ~100%. We recently used finite-element simulation to explore the rupture process of a metal film on an elastomer. The simulation predicted the highest stretchability on stiff elastomeric substrates [1]. We now report experiments designed to verify this prediction. A ~15-μm thick sili...
