Foldable FRP plate and manufacturing method thereof
12434446 · 2025-10-07 · ·

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 multilayer body for rolling includes a layer A and a layer B. The body is configured such that: if the sum of the total thicknesses of layers A and B is taken as 100%, the total thickness of layer A is from 0.5% to 10% (inclusive) and the total thickness of layer B is from 90% to 99.5% (inclusive), and layer A is arranged in at least one surface. Layer A contains a specific amount of a propylene polymer component, a specific amount of a specific resin component that has a polar group in the molecular chain, and a specific amount of a specific thermoplastic elastomer component that does not have a polar group in the molecular chain. Layer B contains a specific amount of a propylene polymer component and a specific amount of an inorganic filler.
