    Abstract: The present inventive concept relates to a mold and a construction panel manufacturing method using same, in which, in order to manufacture a construction panel, a surface on which a raw material is applied is formed into a curved surface by continuously connecting a rope. The mold comprises: first and second side plates facing each other; a curved base forming a predetermined curved surface between the first and second side plates by being interweaved to the first and second side plates; and a sheet member disposed along the curved base so as to form the curved surface, and enabling a construction panel raw material to be applied thereon. Thus, construction panels having variously-shaped curved surfaces may be manufactured by repeatedly using the first and second side plates while differing the interweaving of a rope so as to correspond to a curved surface of a construction panel to be manufactured. Accordingly, the present inventive concept has the effect of having excellent manufacturing efficiency for construction panels having curved surfaces.

    Abstract: The importance of architectural asymmetry is investigated to improve the output voltage of TENGs with polyester/spandex blend three-dimensional (3D) spacer fabrics. Different types of TENGs are fabricated by stacking the 3D spacer fabrics, polydimethylsiloxane (PDMS) films, and electrodes with different stack configurations. The 3D spacer fabric TENGs fabricated with higher architectural asymmetry show higher output voltages than those fabricated with lower architectural asymmetry. In particular, the TENG with the PDMS/fabric/fabric configuration shows the highest peak-to-peak output voltage among all types. An increase in the TENG output voltage is attributed to the relatively high architectural asymmetry in the device configuration and the relatively high effective density of triboelectric charge.
