Stresses in Shape Memory Polymer-matrix Nanocomposites for Biomedical Applications
We report on the residual stresses in amorphous shape memory polymers reinforced with SiC particles. After 50% compression of the composite material at 25 °C, the SiC particles exhibit a compressive stress, which is almost completely released during heated recovery at 120 °C. The residual stresses in SiC hexagonal (6H) phase were estimated through the average change of the unit-cell volume. Lat...
متن کاملMedical applications of shape memory polymers.
Shape memory polymers (SMP) are lightweight, have a high strain/shape recovery ability, are easy to process, and required properties can be tailored for variety of applications. Recently a number of medical applications have been considered and investigated, especially for polyurethane-based SMP. SMP materials were found to be biocompatible, non-toxic and non-mutagenic. The glass transition tem...
متن کاملAn experimental investigation on the energy storage in a shape-memory-polymer system
In this paper, the effect of thermomechanical loading on the behavior of deflection-based harvested energies from a shape memory polymer system is experimentally investigated. Samples are created with honeycomb cells from poly-lactic acid using additive manufacturing techniques. The shape memory effect in shape recovery and force recovery paths are studied under thermomechanical tests in bendin...
متن کاملShape-Memory Polymer Composites
The development of shape-memory polymer composites (SMPCs) enables high recovery stress levels as well as novel functions such as electrical conductivity, magnetism, and biofunctionality. In this review chapter the substantial enhancement in mechanical properties of shape-memory polymers (SMPs) by incorporating small amounts of stiff fillers will be highlighted exemplarily for clay and polyhedr...
متن کاملShape memory alloy micro-actuators for medical applications
Most of the current ’applications’ of microelectromechanical systems can be found in the sensor field. The development of micro-actuators is severely hindered by the low power-to-volume ratio of most actuator technologies. Most of the presented micromotors also require reduction gearing and suffer from wear or fatigue problems. Shape Memory Alloy (SMA) actuators offer the advantage of extremely...
