The invention resides in a novel ignition resistant activated biregional fiber that is extremely flexible due to the presence of an inner core of a thermoplastic polymeric composition in the fiber that is surrounded by an outer sheath of activated carbon. The invention also discloses a process for the manufacture of flexible activated biregional fiber(s) by heating oxidation stabilized biregional fibers or carbonaceous biregional fibers in an activating atmosphere for a period of time and at a temperature sufficient to form an activated carbonaceous outer region in the fiber while the inner core of the fiber remain as a thermoplastic polymeric composition. The activated biregional fibers are particularly characterized by having a highly porous internal structure with an internal surface area of from about 50 m /g to greater than 2000 m /g depending on fiber diameter. Preferred end uses for the biregional activated carbon fiber(s) include, for example, air and water purification, solvent recovery, waste water treatment, the removal of noxious gases such as sulfur dioxide from stack gases, gas separation and storage, etc.

A low resistance electrical connection is disclosed to connect two dissimilar electroconductive materials, one of which is a fiber, bundle of fibers or a film of an electroconductive polymer, carbon or graphite to an electroconductive metal collector. The connection is achieved by electroplating at an initial low current density the edge ends of a fiber or bundle of fibers or the edges of a cloth or film with an electroconductive metal, e. g. copper, silver and the like; thereafter crimping a fine electroconductive wire mesh onto said plated area and then continuing the said plating process until the wire mesh or gauze is substantially encapsulated with said electroplated metal. Alternative, the electroplated fiber ends may be joined by solder, as by dipping the ends or edges into a molten solder bath or laying a bead of solder substantially onto the copper plated edge of the fiber, bundle, cloth or film. Such practice ensures the electroconductive polymer, carbon or graphite end or edge will be intimately bound to the electroconductive metal forming the collector or frame. In many instances it is necessary that the collector metal and/or frame be insulated both electrically and chemically from contact with the environment into which the electroconductive polymer, graphite, carbon and the like is to be used.

The present invention is concerned with a composite material matrix of a synthetic or natural resin with a reinforcement of a multiplicity of lightweight, resilient shaped reforming elongatable, non-linear, non-flammable carbonaceous fibers. The fibers preferably have a sinusoidal or coil-like shape, a reversible deflection ratio of greater than 1. 2:1 and an aspect ratio (1/d) greater than 10:1. The fiber-reinforced composite material of the present invention possess excellent impact resistance properties.
