Shape memory effect in the epoxy polymer composites with aggregated filler
Tóm tắt
The specific features of the stress-induced shape memory effect are studied for composites based on various polymers and fillers, which can form aggregates and are capable of marked compaction. The appropriate deformation schemes make it possible to prepare composites with different structural states, which give various signs and ratios between longitudinal and transversal strains upon shape recovery. The criterion is proposed for estimating the ability of the composite for shape recovery with marked volume changes: the relative density of the filler defined as the ratio of powder density and compacted powder density.
