Different amounts of sepiolite and colemanite (1, 3, 5 and 10 wt.%) were used as sustainable fillers. The mechanical and thermal properties, as well as shape memory behavior of the composites were investigated by tensile tests, differential scanning calorimetry (DSC) analysis, and bending tests, respectively. The results showed that the tensile strength of the epoxy increased with increasing filler content. The glass transition temperature (Tg) decreased in the presence of PEG and fillers. The epoxy composites exhibited good shape memory performance. The recovery time of all the composites decreased with increasing temperature. The optimum temperature was found to be at 110°C in the case of the shape memory cycle tests. The recovery values (Rr) of the composites cured with MNA and cycloaliphatic polyamine were 99% and 98%, respectively. Ten consecutive shape memory cycles have been successfully conducted for the epoxy composites including sepiolite. © 2025 Wiley Periodicals LLC.eninfo:eu-repo/semantics/closedAccessArticle10.1002/app.569102-s2.0-105003264258
