Abstract:
1. A method for applying adhesive and brazing material to a honeycomb structure, which comprises: providing the honeycomb structure with at least one at least partially textured film having a pitch and a wave height defining a corrugation; selecting an average brazing material diameter of a powderous brazing material that is smaller than 15% of the wave height; determining a minimum adhesive strip width according to the equation: where B is the adhesive strip width, D is the average brazing material diameter, P is the pitch, and W is the wave height; applying an adhesive at least to the at least partially textured film within the adhesive strip width on at least some corrugation peaks formed by the corrugation; and applying brazing material to the honeycomb structure.
