为了设计用于空间应用的形状记忆环氧泡沫驱动器，选择了三种不同的构型：压缩、弯曲和扭转。样品是通过固态发泡的方法制造的，并进行了多次恢复试验来测量作为温度函数的致动载荷。由于报道的结果，在奋进号航天飞机的最后一次任务中，形状记忆环氧泡沫的原型被选作在国际空间站进行的一项实验。(C)2011爱思唯尔B.V.保留所有权利。
In order to design an actuator in shape memory epoxy foam for space applications, three different configurations were chosen: compression, flexure and torsion. Samples were produced by means of solid state foaming, and multiple recovery tests were carried out to measure the actuation load as a function of the temperature. Thanks to the reported results, prototypes of shape memory epoxy foams were selected for an experiment on the International Space Station during the last mission of the Space Shuttle Endeavour.
