    摘要: The invention relates to a method of surface treatment of predetermined areas of a composite material structure with at least one plasma beam at atmospheric pressure, produced by a plasma generator provided with an emission nozzle in order to facilitate its adhesive bonding to another structure, in which: a) the plasma beam emitted through the nozzle may include a reactive gas, is projected on the composite material structure from a distance comprised between 0,2 and 10 cm; b) the plasma beam is projected on the composite material structure with an angle of incidence comprised between 75° and 105°. It is preferably applied to carbon fiber or fiberglass and epoxy resin or bismaleimide resin structures. Other relevant variables in the process are the plasma beam power and the treatment rate.
