Abstract

Light activated shape memory polymer (SMP) composites are significant in developing breakthrough technological advancements since the shape memory effect can be remotely controlled by light. This paper presents the structural performance and photothemeral recovery behaviour of 0/90 woven carbon fibre reinforced shape memory polymer composite (SMPC). The structural performance of SMP has increased significantly due to carbon fibre reinforcements as anticipated. The SMPC specimens were exposed to three different power densities of 808 nm near infrared radiation and respective temperature variations and shape recovery behaviours have been observed. The results revealed that, beside the typical activation by heating, the SMPC can be activated by photothermal heating, as a result of its ability to absorb near infrared radiation. This study has evidently shown the ability of carbon fibre reinforced SMPCs for space engineering applications. Accordingly, two prospective applications of carbon fibre reinforced SMPCs, i.e. a deployable space habitat and a deployable hinge for a solar panel of a satellite are presented.
