Shape Memory Polymer Composite (SMPC) Based Thin Shell Structures for Modular Construction of Deployable Habitats
15 SEP 2022
10.00 AM - 11.30 AM
With recent advances in shape memory polymer reinforced composites (SMPCs) in a variety of applications including deployable structural components, open up many windows of opportunities in space exploration field. These structures can be manufactured in required shape, programmed to take less volume inside the payload and deployed on an extraterrestrial location. 
Designing and building lunar habitats have been happening conceptually and experimentally with rigid and deployable habitat technologies over the past decades. On the context of deployable structures, the SMPCs will be ideal materials for lunar habitat building with both rigid and deployable properties. 
This project proposes an innovative framework to develop an easily programmable, recoverable, and attachable SMPC-based hemispherical thin shell dome structure or/and cylindrical shell as a part(s) of a modular habitat unit to match the lunar environmental conditions. For this purpose, synthesis of the SMPC will be done using cyanate-ester and epoxy-based materials and reinforcing fibres. Attachable SMPC dome pieces will be fabricated with vacuum resin infusion technology. 
The concept is planned to be proven by evaluating thermomechanical properties, shape memory effect and durability of the SMPC mimicking the lunar environmental conditions by a series of tests and FEA simulations for the validation of a scaled-up model.
