Research on Properties of Dopamine and Silicon Carbon Black Modified Basalt Fiber Reinforced Magnetorheological Elastomer

The basalt fibers (BF) and the basalt fibers etched by H(2)SO(4) (BF(H)) were modified by polydopamine (PDA) or synergistically modified by PDA and silicon carbon black (SiCB). The effects of modified BF, BFH and SiCB on the basic mechanical properties and magnetorheological (MR) effects of natural...

Sumario:The basalt fibers (BF) and the basalt fibers etched by H(2)SO(4) (BF(H)) were modified by polydopamine (PDA) or synergistically modified by PDA and silicon carbon black (SiCB). The effects of modified BF, BFH and SiCB on the basic mechanical properties and magnetorheological (MR) effects of natural rubber/butadiene rubber-based magnetorheological elastomer precursors (MREs) were investigated. The results show that the tensile strength, tear strength and stress at 300% strain of MREs/PDA-BF(H)-SiCB prepared with BF(H) synergistically modified by PDA and SiCB reach the maximum values, which are 9.58 MPa, 24.07 kN/m and 4.13 MPa, respectively. Additionally, its MR effect is more than three times higher than that of MREs before composite modification.
