The Shape Memory Composite (SMC) belt composed of two kinds of SMAs with different phase transformation temperatures and SMP was fabricated and the three-way (reciprocating) movement in bend actuation were investigated. The results obtained can be summarized as follows. (1) Two SMAs (showing shape memory effect and superelasticity) and three SMPs were used for fabrication. The shape-memorized round alloy tapes were arranged facing in the opposite directon and were sandwiched by one SMP tape in the central part and by two SMP tapes from upper and lower sides. The laminated SMC belt was fabricated without bubble and gap by using the appropriate factors. (2) The three-way bend movement was achived during heating and cooling based on the characteristics of the SMA tapes and the SMP tape. (3) By the combination of the SMAs and the SMPs, the development and application of multi-functional SMCs with simple structure for three-dimensional actuators are highly expected.
