The assembly includes a first subassembly of molded composite material and a second subassembly of molded composite material. An adjustable mating interface couples the subassemblies together. The interface includes a groove and a flange disposed on the first subassembly and bonded within the groove. The groove is sized and shaped relative to the size and shape of the flange to allow a bonding position of the flange within the groove to be adjusted during assembly of the subassemblies so that the mating interface is adjustable. ## Claims ### Claim 1 An assembly of subassemblies having a mating bond interface for a motor vehicle, the assembly comprising: a composite molded first subassembly; a composite molded second subassembly; and an adjustable mating interface for coupling the subassemblies together, the interface including a groove and a first flange disposed on the first subassembly and bonded within the groove wherein the groove is sized and shaped relative to the size and shape of the first flange to allow a bonding position of the first flange within the groove to be adjusted during assembly of the subassemblies so that the mating interface is adjustable wherein the first subassembly includes a first opening which extends into an interior of the first subassembly from an exterior of the first subassembly, the first flange extending about the periphery of the first opening. ### Claim 2 (depends on 1) The assembly as claimed in claim 1 wherein the second subassembly includes a second opening which extends into an interior of the second subassembly from an exterior of the second subassembly, the groove of the interface extending about the periphery of the second opening and wherein the openings are in fluid communication with one another. ### Claim 3 (depends on 1) The assembly as claimed in claim 1 wherein the first and second subassemblies are adhesively bonded together by an adhesive disposed within the groove. ### Claim 4 (depends on 1) The assembly as claimed in claim 1 wherein the composite material of the first and second subassemblies comprises multiple plies of fiber-reinforced composite material. ### Claim 5 (depends on 4) The assembly as claimed in claim 4 wherein the composite material is carbon-fiber reinforced plastic (CFRP). ### Claim 6 (depends on 1) The assembly as claimed in claim 1 wherein the interface includes a second flange received within the first opening for locating the subassemblies relative to each other during assembly of the subassemblies. ### Claim 7 (depends on 1) The assembly as claimed in claim 1 wherein the composite material of the first and second subassemblies comprises multiple layers of fiber, prepreg sheets which are compression molded. ### Claim 8 (depends on 7) The assembly as claimed in claim 7 wherein each of the subassemblies is made of woven carbon fiber, prepreg material. ### Claim 9 (depends on 2) The assembly as claimed in claim 2 wherein exterior surfaces of the subassemblies are class A, automotive vehicle surfaces. ### Claim 10 (depends on 1) The assembly as claimed in claim 1 wherein the second subassembly includes a second opening which extends into an interior of the second subassembly from an exterior of the second subassembly, wherein the first opening of the first subassembly and the second opening of the second subassembly are in fluid communication with one another; and the interface further includes a second flange disposed on the second subassembly, the second flange extending about the periphery of the second opening of the second subassembly and at least partially defining the groove, and the second flange being received within the first opening of the first subassembly for locating the subassemblies relative to each other during assembling of the subassemblies.
