▎ 摘　　要

NOVELTY - Composite structure comprises a substrate layer (100) and a functional layer set on at least one side surface of the substrate layer. The substrate layer comprises a first supporting part (101), a second supporting part (102) arranged in parallel, and a bendable connecting part (103) set between the first supporting part and the second supporting part, and connected with the first supporting part and the second supporting part. The material of the first supporting part and the second supporting part comprises hard rubber fiber composite material. The functional layer comprises a conductive layer, a thermally conductive layer and an impact resistant layer. The conductive metal comprises copper, silver, gold, nickel and/or tin. The thermally conductive layer includes thermally conductive silica gel sheet, thermally conductive silicone grease, thermally conductive double-sided tape, thermally conductive graphite sheet, graphene sheet, and/or graphene oxide sheet. USE - The composite structure is useful for flexible screen assembly of a foldable terminal. ADVANTAGE - The composite structure can provide good rigid support for the flexible screen, and is light in weight and low in cost, can effectively realize functions e.g. electric conduction, thermal conduction, and impact resistance, and improves the product competitiveness of foldable terminals. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: a flexible screen assembly used in a terminal; and a foldable terminal. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic structural diagram of the flexible screen support structure. 100Substrate layer 101First supporting part 102Second supporting part 103Bendable connecting part 200Functional layer
