In a system and method for making a capped structure having a variegated cap layer a layer of cap materials is applied to a substrate and pin stripes are applied onto the cap layer through an extrusion die. After these materials exit the extrusion die they are passed through a single opening in a die plate to create a capped structure having a variegated appearance. This capped structure has a smooth surface that enables an embosser to create a consistent embossing pattern on the entire surface.

The present disclosure provides a metamaterial manufacturing method. The manufacturing method includes the following steps: (a) separately adding insulating substrate powder and at least one of wave-absorbing agent powder and metal electrode powder to thermoplastic resin, and mixing them evenly to obtain a raw material; (b) applying a coextrusion process to the raw material according to a metamaterial microstructure design, to form a microstructure unit rodlike material; and (c) configuring the microstructure unit rodlike material in a cyclic microstructure configuration manner, placing the material in an extruder, and obtaining a cyclically configured metamaterial microstructure through coextrusion by using the extruder. The present disclosure further provides a metamaterial manufactured by using the foregoing method. The present disclosure provides a method for manufacturing a ceramic-substrate metamaterial that features high efficiency, low iteration costs, and a relatively high yield rate. A thinner and more efficient wave-absorbing metamaterial is obtained.

The invention relates to a method of manufacturing a shell part (101) for a wind turbine blade also comprising an add-on component (301, 302) connected to the shell part (101) along a connection face. The method comprises the steps of providing an insert (102) with a side surface of approximately the same shape as the connection face, positioning the insert in an open mould, and placing one or more layers (105) of material in the mould (103) to form the shell part (101) wherein the layers (105) are placed in abutment to the side surface (104) of the insert (102) thereby forming a side surface (108) of the shell part (101) of approximately the same shape as the connection face. After resin cure, the insert (102) is removed. The invention further relates to a method of manufacturing a wind turbine blade shell member (100) comprising such a shell part (101), and layers (105) of material are placed in the mould (103) in abutment to the side surface (108) of the shell part (101) to form the add-on component (301, 302).
