TLDR
In this article, a composite joint system is disclosed in which a composite structure containing carbon fibers embedded in a copper matrix in any configuration, e.g. in one direction, in random directions, in mesh form, spirally or radially is joined to another structure through a brazing material such as solder, Al brazer or Agbrazer.Abstract:
A composite joint system is disclosed in which a composite structure containing carbon fibers embedded in a copper matrix in any configuration, e.g. in one direction, in random directions, in mesh form, spirally or radially is joined to another structure through a brazing material such as solder, Al brazer or Ag brazer. A film of metal such as Ni, Cr, Mo, W, Ta, Ti, Zr, V, an alloy of one or some of such metals, or the combination of some thereof is interposed between the composite structure and the brazing material. The metal film has a good wettability to both the composite structure material and the brazing material.read more
