Abstract

See full text

A method for restoring a programmed article which contains a shape memory composite material of at least one shape memory polymer network with thermally inducible triple shape properties, the method comprising subjecting the article to a magnetic alternating field and simultaneously to an external heat supply in order to trigger the restoration, wherein at least one of the parameters of magnetic field strength (H) and ambient temperature (TUmg) is increased continuously or discontinuously in such a way that the article first experiences a transition in shape from the first temporary shape (TF1) into the second temporary shape (TF2) and subsequently from the second temporary shape (TF2) into the permanent shape (PF).
