Fiber reinforced composites are increasingly used in high value applications. A novel technology (NanoWeld®) enhancing the structural integrity of interlayer has demonstrated promising results; however, manufacturing issues related to scalability need be overcome. The developed relies on consolidating thermoplastic nanofiber nonwoven veils onto technical dry fabrics through roll-to-roll ultraso...

High-performance electromagnetic interference (EMI) shielding material that can function properly under extreme working conditions is critical for their practical applications. Herein, flexible and highly conductive meta-aramid (PMIA) nonwoven fabrics were fabricated by combining polydopamine (PDA) modification electroless silver plating. The PDA greatly enhanced the efficient deposition of nan...

Recent studies of impinging jet flows have shown that momentum exchange and heat transfer can be significantly improved if the jet flow is pulsed (Zumbrunnen, 1996). Moreover, when the jet holes are elliptical, jet free surfaces are formed into a helical structure. Upon pulsating the jet flow, the helical structure rotates and a strong twisting action can be imparted where the jet strikes a sur...

In this study, based on the shortcomings of previous studies, thermal conductivity and resistance analyzes as well absorptivity thickness parameters fabrics made basalt fiber were evaluated in terms end use according to different application areas such clothing, automotive, insulation, reinforcement filtration. During fabric obtained from rocks Ukraine was subjected several measurement conducti...

Bioaerosols are common biological factors in work environments, which require routine use of filtering respiratory protective devices (FRPDs). Currently, no studies link humidity changes in the filter materials of such devices, during use, with microorganism survivability. Our aim was to determine the microclimate inside FRPDs, by simulating breathing, and to evaluate microorganism survivabilit...

A new approach to odor and pH control in medical and hygiene care applications relies on a treatment of absorbent fluff with selected enzyme inhibitors. Cellulose fiber was found to be a convenient carrier for some chemicals which modify the structure of an enzyme and/or block its active site. In an absorbent system exposed for example to body liquids containing urea, selected substances, when ...
