Abstract: A manufacturing method of a thermoplastic continuous-discontinuous fiber composite sheet is provided, including providing a thermoplastic composite including a continuous fiber and a first thermoplastic resin. A mechanical treatment is performed on the thermoplastic composite to form a plurality of fragments such that the continuous fiber is changed into a discontinuous fiber. At least one thermoplastic discontinuous fiber aggregate layer is formed using the plurality of fragments as a raw material. The at least one thermoplastic discontinuous fiber aggregate layer is thermally compressed with at least one thermoplastic continuous fiber layer.
