Polymer Matrix Composites with Shape Memory Properties

Abstract:

Shape memory composites and structures were produced by using carbon fiber reinforced prepregs and a shape memory epoxy resin. The matrix of the prepregs was an epoxy resin as well but without remarkable shape memory properties. This way, two different technical solutions were adopted. Shape memory composite tubes and plates were made by adding a shape memory layer between two carbon fiber reinforced skins. An optimal adhesion between the different layers was achieved thanks to the compatibility of the prepreg matrix and the shape memory material. Shape memory composite structures were also produced by joining composite shells with shape memory foams. Mechanical, dynamic mechanical and shape recovery tests were carried out to show the properties of the composite materials and structures. Results confirm the ability of this class of materials to easily change their shape without affecting the mechanical stiffness of the recovered structures.
