4D printing of PLA/PCL shape memory composites with controllable sequential deformation

2 days ago   |   By Springer

Abstract
Shape memory polymers are a promising class of materials for biomedical applications due to their favorable mechanical properties, fast response, and good biocompatibility. However, it is difficult to achieve controllable sequential shape change for most SMPs due to their high deformation temperature and the simplex deformation process. Herein, shape memory composites based on polylactic acid matrix and semi-crystalline linear polymer polycaprolactone are fabricated using 4D printing technology. Compared with pure PLA, with the rise of PCL content, the 4D-printed PLA/PCL...

Uniaxial tensile deformation behavior of a sandwich-like structural TiNb-NiTi composite for biomedical applications

2 days ago   |   By Springer

Abstract
The uniaxial tensile deformation behavior of a sandwich-like structural TiNb-NiTi composite was investigated by uniaxial tensile test and in situ high-energy synchrotron X-ray diffraction. It is found that below 1.2% macroscopic strains, the elastic deformations of the B2, β, B19′ and α″ phases take place in the TiNb-NiTi composite. During the subsequent loading, the β → α″ and B2 → B19′ stress-induced martensitic transformations occur within the macroscopic strains of 0.5%-4.2% and the macroscopic strains of 0.7%-6.2%, respectively. At the macroscopic strain of about 4.2%, the...
