Multilayered Composite Plates with Shape Memory Properties

Article Preview

Abstract:

In this study, multilayered composite plates with shape memory properties were produced: carbon fibers prepreg are alternated with layers of shape memory epoxy powder obtaining composite with different number of layers. The differences in the load exerted during shape recovery, and percentage and time of recovery of the composites as a function of layers number have been evaluated. In particular, the actuation load and the shape recovery percentage were measured after a V-shape memorizing step of the composites. The experimental results are very promising, showing that such multilayers can successfully recover the original shape without noticeable damages and an increasing of actuation load per layer has been found at the increase of the layers number.
