Bonded functionally graded material structure for heat transfer and CTE matching and method of making same

A method for producing a bonded Functionally Graded Material (FGM) structure, comprising:

• providing a plurality of dissimilar material layers including a top dissimilar material layer and a bottom dissimilar material layer and a plurality of intermediate dissimilar material layers;
• forming a first group of through holes and a second group of through holes arranged alternately on the plurality of intermediate dissimilar material layers and forming a first group of blind holes and second group of blind holes arranged alternately on the bottom dissimilar material layer, wherein the first group of through holes has a diameter larger than a diameter of the second group of through holes;
• cleaning surfaces of the plurality of dissimilar material layers;
• stacking the plurality of dissimilar material layers on top of one another consecutively from a bottom dissimilar material layer to a top dissimilar material layer, wherein a first group of through holes on any dissimilar material layer is arranged corresponding to a second group of through holes on a dissimilar material layer stacked above, and a second group of through holes on any dissimilar material layer is arranged corresponding to a first group of through holes on a dissimilar material stacked right below;
• and
• bonding the plurality of dissimilar material layers using a bonding process.
