Shape memory fixity
Webb28 aug. 2024 · This ability allows the fibers to have shape memory behavior. We systematically characterized the shape memory behavior of the SEBS fiber filled with … WebbThe shape transition temperatures of SiCw/epoxy composites decreased slightly with the increase in SiCw content, but it was noted that all of the composites showed excellent shape memory properties. The shape fixity ratio increased as SiCw content increased (>99%), and the shape recovery ratio slightly decreased as SiCw content increased (>95%).
