Applications for shape-memory polymer composites in aerospace
- Applications for shape-memory polymer composites in aerospace .............. p56 - The importance of damage tolerance in aerospace structures ................... p58 The applications for shape-memory polymers and composites in aerospace have been widely studied since the 1980s. As shown in this paper, these promising smart materials are being particularly developed and qualified for space deployable structures, morphing structures, smart mandrels, optical reflectors, smart textiles and fabrics.

hape-memory polymers (SMPs) are able to respond to a specific external stimulus by means of certain significant macroscopic properties such as shape. The basic molecular architecture of SMPs is a polymer network underlying the active movement. An SMP must consist of dual-segments, one that is highly elastic and another that is able to reduce its stiffness upon a particular stimulus. The latter can be either molecular switches or stimulus-sensitive domains. Upon exposure to a specific stimulus, the switching/tran-
sition is triggered and strain energy stored in the temporary shape is released, which consequently results in shape recovery. SMPs undergo significant macroscopic deformation upon the application of an external stimulus (e.g., heat, electricity, light, magnetism, moisture and even a change in pH value) [1 - 2 ]. Thermo-responsive SMPs are the most common. At a macroscopic level, as illustrated in Figure 1, the typical thermomechanical cycle of a thermo-responsive SMP consists of
