WebJun 22, 2024 · The proposed shear thickening fluid (STFA) has been developed in order to improve compatibility, and impact response capability of NR foam. Although maximum apparent viscosity and shear stress of STFA have lower than those of ST0, the impact absorption capability of STFA/NR foam was higher than of STF0/NR foam.
WebJul 1, 2024 · Up to date, a considerable experimental work has been performed to reveal the impact behavior of polymer foam core sandwich composites. Though, a few attempts have been made to integrate shear thickening fluids (STF) in closed cell rigid polyurethane foams (PU). STF possess a unique rheological property providing a rapid response to …
