Claim Text:
1. A method for manufacturing a multilayer structure using a feedblock multiplier with thickness-gradient variation, comprising: inputting materials; transporting the materials to a feedblock section of the feedblock multiplier with thickness-gradient variation, and the materials being split into fluids over a plurality of the feedblock section; the fluids over the channels transported to a segmenting section defining a bevel or a curved cross section configured to define the multiple of layers and render the thickness-gradient variation, and segmented into two or more fluid segments by the bevel or the curved cross section of the segmenting section, and each fluid segment including fluids segmented over the plurality of channels; the two or more fluid segments individually flowed over two or more channel-switching sections and combined in a multiplier section, wherein the two or more channel-switching sections are used to switch relative transportation position of the channels in each channel-switching section, and the thicknesses of the channels over the channel-switching sections have gradient variation; the fluids over the channels of the each fluid segment stacked up at the multiplier section; and the fluids over the channels of the multiplier section outputted at an extruding section, and producing a multilayer structure with the thickness-gradient variation including a plurality of layers of materials.
