Abstract:
1. A method of bonding a composite, comprising: exposing a surface of a composite work piece to a reactive gas beam from a low-temperature, atmospheric pressure plasma delivery device; applying epoxy adhesive to at least a portion of the surface after exposure to the reactive gas beam; and joining the composite work piece to a second work piece with the applied epoxy adhesive; wherein the low-temperature, atmospheric pressure plasma delivery device generates the reactive gas beam by application of electrical power across at least a pair of electrodes in contact with approximately 0.1 vol. ° A) to less than 2 vol. % mixture of either oxygen or air at atmospheric pressure flowing between the pair of electrodes to become the reactive gas beam and projects the reactive gas beam exterior to the low-temperature, atmospheric pressure plasma delivery device from a showerhead through a plurality of holes.
