abstract

Shape memory polymers (SMPs) have garnered significant attention in recent years for their potential to return to a “memorized” state when warmed above their glass transition temperature Tg . However, they also have potential in morphing aircraft applications because of their significant modulus change above and below Tg . Much less energy is required to deform this material when in its soft state, but when the material returns to the hard state, it is able to support significant loads. In the proposed effort, SMP is experimentally considered as a candidate material for morphing aircraft applications where the material’s ability to support out of plane loads above and below the Tg is of primary importance. The SMP of study in the work is Veriflex®.
