Abstract
A fibrous sheet having the shape memory property which comprises a sheet made of natural fiber and/or synthetic fiber and a layer formed by applying a powder of shape memory polymer; and a method of imparting the shape memory property which comprises applying a powder of shape memory polymer to a desired part of a product of a sheet made of natural fiber and/or synthetic fiber by the aid of a resin adhesive.
Claims10
A fibrous sheet having a shaped memory property which comprises a sheet made of natural fiber and/or synthetic fiber and a shaped memory polymer layer formed by a powder of shape memory polymer applied to the sheet fiber, the polymer undergoing large changes in its modulus of longitudinal elasticity around its glass transition point temperature, the polymer restoring the fibrous sheet to its original shape when heated to a temperature higher than the glass transition point temperature.
A method of imparting a shaped memory property to a sheet product which comprises applying a powder of shape memory polymer to a desired part of a sheet product made of natural fiber and/or synthetic fiber, the shaped memory polymer undergoing changes in its modulus of longitudinal elasticity around its glass transition point temperature, the applied polymer restoring the sheet product to its original shape when heated to a temperature higher than the glass transition point temperature.
