“…The development of the SMA-containing SMEP hybrids started with the investigations of laminated beams [178,208,209,210] followed by 2D (shell) [211,212] and 3D structures [213] and devices [178]. These works contributed to clarify open issues with respect of embedding, positioning, content, maximum straining, minimum bending radius, actuation capability-related properties, etc.…”

Shape memory polymer (SMP) is capable of memorizing one or more temporary shapes and recovering successively to the permanent shape upon various external stimuli. Beside of the above mentioned one-way variants, also two-way shape memory polymers (SMPs) and shape memory (SM) systems exist which feature a reversible shape change on the basis of "on-off switching" of the external stimulus. The preparation, properties and modelling of shape memory epoxy resins (SMEP), SMEP foams and composites have been surveyed in this exhaustive review article. The underlying mechanisms and characteristics of SM were introduced. Emphasis was put to show new strategies on how to tailor the network architecture and morphology of EPs to improve their SM performance. To produce SMEPs novel preparation techniques, such as electrospinning, ink printing, solid-state foaming, were tried. The potential of SMEPs and related systems as multifunctional materials has been underlined. Added functionality may include, among others, self-healing, sensing, actuation, porosity control, recycling. Recent developments in the modelling of SMEPs were also highlighted. Based on the recent developments some open topics were deduced which are merit of investigations in future works.

“…Thus, the phase transformation is accompanied by large recoverable transformation strains, which lead to the generation of considerable stresses. For these reasons, several studies [4,8] deal with SMA elements embedded in composite structures: through implementation inside the polymeric host structure they pull on the skin due to deformation.…”

“…The consecutive relations of the SMA layer were obtained by using the method of micromechanics. This was experimentally done by Zhou and Lloyd [22] on smart composite beams fabricated with E-glass and carbon fibers. Both single-cycle and multi-cycle thermo-mechanical bending actuations of these beams in the cantilever set-up were characterized experimentally by applying various levels of electric current to the NiTi wires.…”

This article deals with the experimental study of mechanical behavior of an edge-notched steel plate repaired by polymer composite and smart patches. The polymer composite patches are made of Kevlar/epoxy and glass/epoxy or a combination of both. The plate is single edge-notched with a constant length and the repair is done on both sides of the notched plate. Four types of patches are considered according to their lay-ups. Tensile, bending, and impact tests are conducted on the specimens according to ASTM standards. The results obtained are compared with the results for un-notched and un-repaired notched specimens. Patching has a significant effect on the mechanical properties of the notched plate. The best patches in each loading case are reinforced with nickeltitanium shape memory wires and the repaired specimens with these smart patches are again tested in tension, bending, and impact loadings. Smart patches had a more significant effect on the above behavior as compared to composite patches.
