摘要:
In order to provide a layered article in which shape deformation is suppressed while exhibiting compression properties that are an index of impact absorption, and further, a layered article that can control feeling when receiving impact on demand, provided is a layered article including a porous structure material containing discontinuous reinforcing fibers (A), resin (B) and voids (C), and a skin layer formed on a surface of the porous structure material, in which
the porous structure material has an elastic resilience from 50% compression of 1 MPa or more, and
the layered article has a plastic deformation amount of 20 µm or less in a falling-weight impact test performed on the surface on which the skin layer is formed.
