A method for the determination of thermal conductivity polymer composite materials by using Co-based ferromagnetic microwires is proposed. Microwire segments were integrated into samples studied during their manufacture and used as current microheaters resistance thermometers. As a representative material, we material based on nitrile butadiene rubber filled with hexagonal boron nitride after i...

Abstract Diamond-like carbon (DLC) films directly deposited on rubber substrate is undoubtedly one optimal option to improve the tribological properties due its ultralow friction, high-hardness as well good chemical compatibility with rubber. Investigating relationship between film structure and performance vital for protecting In this study it was demonstrated that etching effect induced by hy...

Nylon 6, 6 is regarded as tough and ductile materials since it exhibit high tensile elongation to break and high drop weight impact strengths. However, under conditions of stress concentration such as in the presence of sharp notches or cracks, polyamides exhibit brittle failure. This property, evaluated as notched Izod or Charpy impact tests, indicates that unmodified polyamides exhibit relati...

Abstract The recycling of leather solid waste not only involves resource utilization and environmental protection but also has important significance for the sustainable development industry. In this paper, was crushed into fibers, which were stabilized mixed with nitrile-butadiene rubber (NBR). mixture milled vulcanized a composite NBR-SLF (Stabilized Leather Fiber) is prepared sealing materia...

A better understanding of elastomers’ behavior during Rapid Gas Decompression (RGD) requires advanced knowledge what is happening gas sorption and desorption. This will offer to improve numerical simulation phenomena consider a real environmental use an O-ring, as for thermal applications. previous experimental study developed testing protocols investigate the performance elastomeric O-rings. T...

This study deals with the effect of coupled thermal and cyclic mechanical loadings on the viscoelastic response of carbon black filled nitrile rubber. For this purpose, cyclic loading tests were performed at different temperatures by means of Dynamic Mechanical and Thermal Analysis (DMTA). The type and level of the thermomechanical loadings applied were chosen in order to determine the relative...
