Metallic fibre

Polymers are sometimes used to shield electromagnetic fields for this purpose they can be filled with metal fibres. 

Production of pure metallic fibres. The structure is of the metal, and charge conduction is obtained through the entire fibre. 

An even better effect is created by blending the polymer with metal fibres, e.g. for shielding electric fields. Even a small amount of these fibres is able to form a network, which considerably increases the conductivity. 

Besides for improving mechanical properties, short fibres can also be applied for other purposes, such as electric conductivity. Metal fibres, if dispersed in such a way... 

Compared with a Teflon -bonded commercial electrode, the composite electrode showed lower polarization losses at high current densities, even though the composite material did not contain Pt. The ohmic and mass transfer resistances were lower in the composite electrode than in the commercial electrode. The sintered contacts and interlocked networks formed in the composite structure permitted better electrical and physical contact between the carbon fibres and metal fibres, leading to a composite electrode with a high void volume and large macroscopic porosity, which increased the accessibility of carbon to the reactants [22],...

Bekaert Beklpor WB is a composition of metal fibres, uniformly laid, to form a 3-dimensional nonwoven porous web structure. 

Bekaert Beklpor ST Is a family of uniquely designed metal fibre media, produced by sintering WB. 

Explosive articles include a wide variety of devices or tools that employ explosives which on initiation produce a sudden, powerful expansion of gases used to some mechanical advantage drive turbines, move pistons, shear bolts and wires, operate pumps, and start engines. Often, these articles contain an explosive cartridge, an explosive charge encased in a cartridge case made of metal, fibre, paper, plastic, or other material. 

Another factor that influences the value of pc is the aspect ratios of the metallic filler. Metal fibres, metal-plated glass fibers, and metal flakes can significantly lower the concentration required to achieve isotropic conduction as compared to spherical powders [3]. Values of pc as low as 1 vol % have been reported with stainless steel fibers having an aspect ratio of 750 [37]. 

Filtration can be used to distinguish between dissolved and dispersed components in a colloidal dispersion. Membrane filtration involves passing a suspension through a thin, porous membrane, which is usually polymer or ceramic in nature, but could also be woven fabric or metal fibres. Filtration is also a common method... 

Research in textile electrodes has led to encouraging findings globally and to some product launches. Investigating textile electrodes for medical purposes, Hertleer et al. (2004) demonstrated that heart beat signals obtained from conventional electrodes with electrogel are comparable with knitted textile electrodes made with yams of metallic fibres. No gel was needed for the textile electrode, which can be a benefit in terms of convenience and user comfort. De Rossi et al. (2003) also found that their...

Metal fibre-reinforced glass matrix composites... 

An advantage of these composites is the increased resistance to fibre damage during composite processing which results from the intrinsic ductility of metallic fibres and the possibility of exploiting their plastic deformation for composite toughness enhancement [100]. A penalty is paid due to the relatively low thermal capability and poor chemical resistance of the metallic fibre reinforcement, limiting the application temperature and environment.

B Ensure the steel fibres in the pad matrix material are sufficiently different to the disc material. The necessity for metallic fibres in the pad matrix needs to be justified particularly in sinking hoists where the brake duty includes trail braking and low speed manoeuvring. 

Antioxidants are key ingredients used in the compounding of PE and PP due to the limited stability of PO to high temperatures and ultraviolet (UV) light [47]. Antistatic plastic materials are frequently made by compounding a thermoplastic with a conductive filler, such as carbon black, carbon fibres or metal fibres [48].
