The present invention discloses a foldable FRP plate, comprising a plurality of first regions and one or a plurality of second regions which are integrated in one piece; the second region is located between two adjacent first regions, so that the adjacent first regions being folded and unfolded relative to each other with the second region as a rotating shaft; the first regions are plate-like products manufactured by impregnating fiber woven fabric with resin for curing, are rigid and cannot be folded; the second region is flexible fiber woven fabric and has a width being two times a design thickness of the FRP plate. The present invention also discloses a manufacturing method, including laying the fiber woven fabric according to a design thickness and a layer layout; dividing the first regions and the second region according to an origami design method.

A joined V-belt includes: a plurality of wrapped V-belt portions; and a tie band, in which outer peripheral surfaces of the wrapped V-belt portions are connected by the tie band. Each of the wrapped V-belt portions includes a belt body and a cover fabric covering an outer surface of the belt body. The belt body includes a tension member layer including a tension member, a tension rubber layer laminated on a belt outer peripheral side of the tension member layer, and a compression rubber layer laminated on a belt inner peripheral side of the tension member layer. The tie band includes a short fiber-containing rubber layer in which a short fiber is oriented in a belt width direction, and the short fiber-containing rubber layer includes a plurality of rib portions extending in a belt longitudinal direction.

A method for joining a first component to a second component includes providing a first component with a first joining part receiving section and creating a joining part on and/or in the first joining part receiving section via a generative method. The method also includes providing a second component with a second joining part receiving section, and joining the joining part to the second joining part receiving section of the second component.
