Carrier with localized fibrous insert and methods

A structural reinforcement for an article including a carrier that includes: (i) a mass of polymeric material having an outer surface; and (ii) at least one consolidated fibrous insert (14) having an outer surface and including at least one elongated fiber arrangement having a plurality of ordered fibers arranged in a predetermined manner. The fibrous insert is envisioned to adjoin the mass of the polymeric material in a predetermined location for carrying a predetermined load that is subjected upon the predetermined location (thereby effectively providing localized reinforcement to that predetermined location). The fibrous insert and the mass of polymeric material are of compatible materials, structures or both, for allowing the fibrous insert to be at least partially joined to the mass of the polymeric material. Disposed upon at least a portion of the carrier may be a mass of activatable material.

Dielectric composite with reinforced elastomer and integrate electrode

The present disclosure is directed to dielectric elastomeric composites that include a retainable processing membrane, an elastomer material, and an electrically conductive material. The elastomer layer may be partially imbibed into the retainable processing membrane. The retainable processing membrane may be porous. The retainable processing membrane is compacted in the transverse in direction, machine direction, or in both directions prior to the application of an elastomer material and an electrically conductive material. The compaction of the retainable processing membrane may form structured folds or folded fibrils in the membrane, giving the retainable processing membrane a low modulus and flexibility. In some embodiments, the dielectric composites are positioned in a stacked configuration. Alternatively, the dielectric elastomeric composites may have a wound configuration. The dielectric composites have a total thickness less than about 170 μm. The dielectric elastomeric composites may be used, for example, in dielectric elastomer actuators, sensors, and in energy harvesting.
