Method for producing nanofibres of epoxy resin for composite laminates of aeronautical structures to improve their electromagnetic characteristics

摘要

Method for producing nanofibres of epoxy resin comprising the steps of: dissolving an epoxy resin formulation in a suitable solvent; and forcing the solution containing the epoxy resin formulation through at least one electrified capillary duct (6, 12), wherein a meniscus is formed at the exit of the capillary duct, being a thin charged nanojet (8) emitted from the vertex of the mentioned meniscus, the formulation of the epoxy resin being selected amongst one of the following: a liquid epoxy resin and a curing agent; a liquid epoxy resin, a curing agent and a binder; a solid epoxy resin; a solid epoxy resin and a curing agent; a solid epoxy resin and a binder; a solid epoxy resin, a curing agent and a binder; a liquid or solid epoxy resin partially cured with a latent curing agent; a liquid or solid epoxy resin partially cured with a latent curing agent and a binder.
