The present study investigated the effect of reinforcement on the viscoelasticity ofshape-memory polymer composites (SMPCs) from two different scale views utilizingtwo different techniques. From a nano-scale view, we conducted dynamic viscoelasticsimulations using molecular mechanics simulation models proposed by our researchgroup . These nano-scale simulations could reproduce a clear glass transition fromglassy state to rubbery state in the frequency domain; therefore, they are suitable forstudying the filler effect including interface properties. From a macro-scale view, weconducted experiment dynamic mechanical analysis using woven fabric basedSMPCs. Through comparison of multi-scale analyses, we investigated the importanceof nano-scale analysis for the composites’ design of viscoelasticity.
