Composite cables suitable for use in conjunction with wellbore tools. One cable may include a polymer composite that includes dopants dispersed in a polymer matrix and continuous fibers extending along an axial length of the cable through the polymer matrix, wherein the cable is characterized by at least one of the following: (1) at least a portion of the cable having a density greater than about 2 g/cm3, wherein at least some of the dopants have a density of about 6 g/cm3 or greater, (2) at least a portion of the cable having a density less than about 2 g/cm3, wherein at least some of the dopants have a density of about 0.9 g/cm3 or less, (3) at least some of the dopants are ferromagnetic, or (4) at least some of the dopants are hydrogen getters.

A method of formulating and using pastes, inks or adhesives made of electrically conductive and magnetically polarizable materials bound by a polymeric matrix includes depositing a paste, ink or adhesive at a low temperature, and using the paste, ink or adhesive as an electrically and magnetically and thermally active component, either in a wet or dried state. The polymer matrix provides the deposited product with mechanical properties, which integrate with the electrical and magnetic functions expressed by the other materials in the product. The product can be deposited both on a flexible and a rigid substrate, and can be used directly on the substrate, or in a form released from the substrate. The deposited product may be used as an electromagnetic and thermal component and device, such as an electromagnetic welder, electromagnetic heater, multifunctional material and coating passivating a static electric charge, magnetoresistive sensor, electromechanical relay, or electromechanical actuator.

A compound comprises a resin composition containing an epoxy resin, a phenol resin, a wax, and an imidazole compound, and a metal element-containing powder, wherein the epoxy resin comprises a crystalline epoxy resin, the wax comprises a montanic acid ester, and the content of the metal element-containing powder is 90 mass % or more based on the total mass of the compound.

Additive manufacturing compositions include low-absorbing particles or non-absorbing particles that have an absorbance for wavelengths of 300 nm to 700 nm that is equal to or greater than 0 Au and is less 1.0 Au, such as 0.001 Au≤absorbance≤0.7 Au. Slurries including such particles and an uranium-containing particle and that are used in additive manufacturing processes have an increased penetration depth for curative radiation. Removal of low-absorbing particles or non-absorbing particles during post-processing of as-manufactured products results in pores that create porosity in the as-manufactured product that provide a volume accommodating fission gases and/or can enhance wicking of certain heat pipe coolant liquids. Low-absorbing particles or non-absorbing particles can be functionalized for improved properties, for example, with fissionable material for improved ceramic yields, with burnable poisons or stabilizers for increased homogeneity, with stabilizers for localized delivery of the stabilizer, or with combinations thereof.

Polytetrafluoroethylene filled with FeCo microparticles provides an ultralow wear, magnetic, multifunctional tribological material. For example, PTFE filled with an 5 wt. % of equiatomic, prealloyed FeCo powder resulted in steady state wear rates of 2.7×10.sup.−7 mm.sup.3/Nm, approaching that of PTFE-filled alumina. Comparable wear rates were not recovered for PTFE filled with just iron or cobalt microparticles.
