Abstract: The presently disclosed subject matter relates to the field of electrospun epoxy fibers, a solution for producing the fibers and a system for electrospinning the fibers. This invention further relates to processes of producing the solution and the fibers. By dissolving epoxy in a dielectric solvent, suitable electrospinning conditions are achieved by controlling the degree of epoxy crosslinking in the solution. The fibers are captured on a net screen, with the positive electrode placed behind it. The resulting electrospun fibers exhibit superior mechanical properties in comparison with other epoxy fibers. This improvement in mechanical properties is, in part, due to anisotropic molecular rearrangement resulting from the strong stretching forces induced by electrospinning.
