A conductive composite structure has a conductive interface surface that enhances conductivity and provides corrosion protection by co-curing a metal-mesh gasket adjacent to a metal wire mesh layer in a multi-layer laminate structure. By co-curing metal-mesh gasket and metal wire mesh layers, gasket tear off and non-conductive resin face issues are eliminated. The conductive interface surface may be ablated to expose at least a portion of the metal-mesh gasket and create potential wire-to-wire contact points when complementary interface surfaces are brought together to create a highly conductive contact interface that eliminates or reduces electromagnetic shielding leakage within the conductive interface region.

A doser mounting bracket for coupling a doser to an exhaust gas aftertreatment system component having a sidewall and an exhaust gas aftertreatment system component opening includes a lower surface, an engagement wall, a central structure, an upper surface, and an attachment structure. The lower surface is configured to be held in a position opposing the sidewall. The engagement wall extends from the lower surface. The central structure has an opening that extends therethrough and includes a centering structure that extends from the lower surface and is configured to be received within the exhaust gas aftertreatment system component opening. The attachment structure extends from the upper surface and is configured to be coupled to the doser. The engagement wall is configured to separate the lower surface from the sidewall when the engagement wall interfaces with the sidewall such that a pocket is formed between the engagement wall, the centering structure, and the lower surface.
