Characristics of Shape Memory Composites Combined with Shape Memory Alloy and Shape Memory Polymer
Advanced Materials Research, 2013In order to develop high functionality of shape memory materials, the shape memory composites combined with TiNi wire and shape memory epoxy were prepared, and the mechanical and thermomechanical properties were studied. The results showed the addition of TiNi wire increased the Young modulus and breaking strength both at room temperature and at ...

Multiple Memory Shape Memory Alloys
Advanced Engineering Materials, 2013AbstractUntil now, shape memory alloys (SMAs) have been largely limited to “remembering” a single memory. In other words, monolithic components only possess a single set of functional properties. The current work describes how theorized change to local chemical composition induced through laser processing enables controlled augmentation of ...

A tough shape memory polymer with triple-shape memory and two-way shape memory properties
Journal of Materials Chemistry A, 2014In this study, a tough shape memory polymer network based on polydopamine, poly(e-caprolactone) and diisocyanate was synthesized in three steps. Fourier transform infrared spectroscopy was used to confirm the synthesis process. The tensile tests demonstrated the good mechanical properties of the materials with a tensile modulus and tensile strength ...

Multi-shape memory effect in shape memory polymer composites
Materials Letters, 2012In this work, the multi shape memory effect is studied for two types of thermal active epoxy polymer composites. One of them is called the controlled behavior of composite material (CBCM) which has already been tested as an unsymmetrical active composite and the other one is the conventional symmetrical composite.

Elasticity and Shape Memory Effect of Shape Memory Fabrics
Textile Research Journal, 2008An attempt has been made in this paper to investigate the distinction between shape memory effect and the wrinkle recovery property of cotton fabrics in terms of temperature sensitivity and elasticity. Elasticity is an inherent characteristic of typical wrinkle-free fabrics, because they are suppose to recover after the release of an external force ...

Shape change/memory actuators based on shape memory materials
Journal of Mechanical Science and Technology, 2017Major techniques currently available to implement typical shape memory materials (such as shape memory alloys and polymers) for three basic types of shape switching actuations—one-time shape memory actuation, cyclic shape memory actuation and cyclic shape change actuation—were explored in detail.

Shape memory alloys (SMAs) have the disadvantage that cooling is difficult and the actuating speed during cooling is slow. To resolve this problem, shape memory material actuators that operate only with heating is required. SMAs are characterized by a low apparent Young's modulus below the transformation temperature and a strong shape recovery force ...

Thermoviscoelastic shape memory behavior for epoxy-shape memory polymer
Smart Materials and Structures, 2014There are various applications for shape memory polymer (SMP) in the smart materials and structures field due to its large recoverable strain and controllable driving method. The mechanical shape memory deformation mechanism is so obscure that many samples and test schemes have to be tried in order to verify a final design proposal for a smart ...

Modeling the shape memory effect of shape memory polymer
SPIE Proceedings, 2009Dynamic mechanical analysis (DMA) tests are conducted on the styrene-based shape memory polymer (SMP) to investigate its state transition behaviors. Tensile tests at various constant temperatures are carried out to reveal the stressstrain- temperature relationship of the styrene-based SMP.

MRS Proceedings, 1999
AbstractThree types of shape memory ceramics were introduced. They were the irreversible shape memory silica glass, the reversible shape memory bi-ceramics glass and reversible shape memory silica and Si-C-O glassy fiber samples (the small size change) induced by thermal expansion.
