Solid–Liquid Composites with High Impact Resistance

Abstract Solid–liquid composites (SLCs) with novel thermal/electronic/mechanical properties imparted by programmable and functional liquid inclusions have attracted considerable research interest in recent years, are widely used smart electronics soft robotics. The feasible application of SLCs requires that they exhibit excellent static physical as well dynamic impact resistance to satisfy complex service conditions, such drops impacts. This paper examined the fabricated using microfluidic 3D printing. results split-Hopkinson pressure bar (SHPB) tests showed performance improved terms energy dissipation compared pristine materials. In case strain rates ranging from 100 $$400\,\hbox {s}^{-1}$$ 400 s - 1 , SLC specimen deformed without fracture, its was dominated viscosity inclusions. For 500 $$800\,\hbox 800 fractured determined volume fraction Thus, could be tuned regulating requirements protection against different rates. Furthermore, process fracture under SHPB recorded analyzed a high-speed camera. distributed changed paths crack propagation enhance SLCs. study experimentally verified enhancement SLCs, provided design strategies for developing multifunctional high resistance.
