ABSTRACT
The pure SMPs usually exhibit lower modulus and recovery forces than the shape-memory alloys or shape-memory ceramics, and therefore the unreinforced SMPs are not suitable for many applications that require special performances (e.g., high strength and high recovery force) [1,2]. In order to improve their mechanical properties, the incorporation of various reinforcing llers within SMPs has been investigated. SMPs reinforced by particles
