NOVELTY - Deposition system includes a multi-material print head, a first reservoir of a first compatible material having particles containing chemical elements similar to a first substrate, and a second reservoir of a second compatible material having particles containing chemical elements similar to a second substrate. A third reservoir of an polymer precursor material, and at least one mixer to selectively mix concentrations of the first and second compatible materials and the polymer precursor material to create multiple mixtures, and feed the mixtures to the deposition system. USE - Deposition system for bonding a joint between dissimilar substrate materials. ADVANTAGE - The deposition system identify single regular adhesives that provide strong bonding of dissimilar materials. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of bonding a joint between dissimilar substrate materials, which involves functionalizing a first compatible material having chemical elements similar to a first substrate mixing the first compatible material with a polymer precursor material; functionalizing a second compatible material having chemical elements similar to a second substrate; mixing the second compatible material with a polymer precursor material; using the deposition system to deposit the first and second compatible materials and a polymer precursor material on the joint between the first and second substrate materials, where the first and second materials have gradients in opposite directions. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of bond between dissimilar materials. Gradient adhesive bond (20.) CFRP interface (22.) Region in the middle (24.) Aluminum interface (26.)
