Ferromagnetic shape memory alloys FSMA are key active materials for fast responsive airborne actuators, but the processing cost is rather expensive. IF the hybrid actuation mechanism proposed by Taya is used, we can design cost-effective FSMA composite. This report discusses the design guide for FSMA composites, focusing on several types of actuator, 1 laminated composite plate for bending actuators, and 2 helical spring with optimized cross section for axial actuators. The design guide is given in terms of analytical solutions with closed form. Processing of some of the proposed FSMA composites are also made, and its preliminary data are given.
