Described herein are component compositions comprising a blend of a polymer resin together with silica glass beads. In certain embodiments, the components demonstrate improved abrasion resistance as do the industrial fabrics produced that comprise at least one component of the instant disclosure.

A process for forming an extruded composition using a wet-spin dry-jet technique including forming a dispersion dope by mixing phase change material with a first portion of solvent, and sonicating the mixture, forming a prime dope by combining a first portion of polymer and a second portion of solvent, forming an extrusion composition by combining the dispersion dope, the prime dope and a second portion of the polymer, rolling the extrusion composition, degassing the extrusion composition, extruding the extrusion composition through a spinneret, drying the extruded composition, and quenching the extruded composition. The weight fraction of the phase change material in the extruded composition can be greater than approximately 60%, and preferably greater than approximately 75%.

Fibers, prepreg materials, compositions, composite articles, and methods of producing composite articles are disclosed herein. A fiber may include at least one polymeric fiber and a plurality of carbon nanotubes. The at least one polymeric fiber extends in a lengthwise direction. The at least one polymeric fiber is a nanofiber.

An embolization device may include a fiber section having a plurality of polymeric electrospun fibers and, optionally, a contrast agent. An embolization device may further include a plurality of fiber sections, wherein each fiber section is separated by a linker. A method of deploying such an embolization device may include inserting the embolization device into a vessel. The method may further include applying an electrical current to one or more of the linkers, applying electrothermal heat to at least a portion of the device, or applying force to at least a portion of a delivery vehicle for the device. A method of manufacturing the device may include electrospinning a fiber section, and processing the fiber section by straining, twisting, heating, or shaping it.
