Abstract

Shape memory polymers (SMPs) are a novel class of active polymers that have a unique ability to undergo substantial shape deformation and subsequently recover their original shape when exposed to a particular external stimulus. The relatively low mechanical properties of SMPs are the main drawback that limits their use in engineering applications. However, when reinforced with fibers, SMPs become a smarter structural material that can be stimulated by an external stimulus. With the current increase of interest in space exploration, there has been a significant demand for lightweight and smart materials for space engineering applications. Shape memory polymer composites (SMPCs) are an obvious choice of materials for such applications. The implementation of SMPCs in space engineering applications requires rigorous optimization processes on the material properties and critical design procedures. The transformation of breakthrough SMPC technologies into real-life applications largely relies upon the robust analytical tools used for the initial design studies. In the past few years, many finite element models have been presented for the analysis of SMPCs. The vast majority of such tools required complicated user-defined material subroutines to be integrated with a standard finite element software package, which is incredibly difficult to implement. The subroutines are problem specific and troublesome for a wider range of potential engineering applications. This chapter presents a finite element simulation technique developed to model the thermomechanical behavior of fiber-reinforced SMPCs. Finite viscoelasticity was used to develop the technique, which is able to consider the nonlinear effect due to the large deformation. By using the experimental methods the proposed simulation technique has been validated. Furthermore, the competency of SMPCs for space engineering applications is discussed.
