Characristics of Shape Memory Composites Combined with Shape Memory Alloy and Shape Memory Polymer

Advanced Materials Research, 2013
In 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, 2013
AbstractUntil 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, 2014
In 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, 2012
In 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.

Bioinspired Multichannel Nerve Guidance Conduit Based on Shape Memory Nanofibers for Potential Application in Peripheral Nerve Repair.

ACS Nano, 2020
Repairing peripheral nerve injury, especially long-range defects of thick nerves, is a great challenge in the clinic due to its limited regeneration capability. Most FDA-approved nerve guidance conduits with large hollow lumen are only suitable for short

Elasticity and Shape Memory Effect of Shape Memory Fabrics

Textile Research Journal, 2008
An 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, 2017
Major 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 Properties of Ti-Ni Shape Memory Alloy / Shape Memory Polymer Composites Using Additive Manufacturing

Materials Science Forum, 2021
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 ...
