Anisotropic shape-memory elastomeric composites (A-SMEC) are fabricated by infi ltrating an aligned electrospun fi brous web with an elastomer, and curing. Mechanical testing proves strong anisotropy in Young's modulus ( E Y ), strain-to-failure ( ε f ), and yield stress ( σ y ) observed with averages of E Y = 48.4 and 4.0 MPa, ε f = 198 and 351%, and σ y = 4.6 and 0.9 MPa for longitudinal and transverse loading directions, with respect to the fi brous web's orientation. Shapememory (SM) characterization reveals modest anisotropy in the shape fi xing ratios ( R f ), yet seemingly isotropic shape recovery ( R r ) nearing completeness. Such soft, anisotropic materials may be used in laminated composite elastomers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
