Shape memory polymers (SMPs) are polymeric materials capable of recovering from a ‘fixed’ temporary shape to a ‘memorized’ permanent shape upon exposure to an external stimulus. Two structural elements are required for a polymer to exhibit useful shape memory: a network structure that defines the permanent shape (the ‘memory’), and a switching segment that induces a significant change in the mo...

Shape memory polymer composites (SMPCs) have been manufactured by press moulding of carbon fibre-reinforced (CFR) prepregs with SMP interlayers. SMPC laminates produced different numbers CFR plies (i.e., 2, 4, 6, and 8) thicknesses the interlayers 100 300 µm) for a sum eight combinations. Co-curing prepreg has led to an optimal adhesion structural functional plies, which confirmed following tes...

Shape-memory polymers represent a promising class of materials that can move from one shape to another in response to a stimulus such as heat. Thus far, these systems are dual-shape materials. Here, we report a triple-shape polymer able to change from a first shape (A) to a second shape (B) and from there to a third shape (C). Shapes B and C are recalled by subsequent temperature increases. Whe...
