Popis: The present study investigated the effect of reinforcement on the viscoelasticity of shape-memory polymer composites (SMPCs) from two different scale views utilizing two different techniques. From a nano-scale view, we conducted dynamic viscoelastic simulations using molecular mechanics simulation models proposed by our research group [1]. These nano-scale simulations could reproduce a clear glass transition from glassy state to rubbery state in the frequency domain; therefore, they are suitable for studying the filler effect including interface properties. From a macro-scale view, we conducted experiment dynamic mechanical analysis using woven fabric based SMPCs. Through comparison of multi-scale analyses, we investigated the importance of nano-scale analysis for the composites’ design of viscoelasticity.
