Fig. 4: Structure and property of woven and cut-pile MR fabrics.
From: Vector-stimuli-responsive magnetorheological fibrous materials
a, Photograph of a flexible plain-weave MR fabric with structure diagram at bottom left. b, Moment density of single MR yarn and plain-, twill- and satin-weave MR fabrics. Error bars correspond to s.d. (n = 3). c, Bending rigidity of single MR yarn and plain-, twill- and satin-weave MR fabrics normalized per MR yarn. Error bars correspond to s.d. (n = 3). d, Photographs of a plain-weave MR fabric with the stiff–soft duality. e, Photograph of a soft and conformable cut-pile MR fabric with structure diagram at bottom left. f, Side-view photographs of the cut-pile MR fabric showing in-plane shearing and out-of-plane stiffening under specific magnetic field directions. g,h, Shear force (g) and compression modulus (h) of cut-pile MR fabrics with specific yarn densities. Error bars correspond to s.d. (n = 3). i, Compression fatigue test on MR fabrics at a frequency of 1 Hz with an extension of 1.5 mm for more than 10,000 consecutive cycles, under specific magnetic fields with a strength of 140 mT. Scale bars, 10 mm (a,d,e,f).
