Significantly enhancing fracture toughness of epoxy composite with promising γ-FeOOH@Fe2O3 hybrid nanoparticles by magnetic field assistance
文献摘要：
The toughening of epoxy resin(EP)and the interlaminar toughening of carbon fiber reinforced composite(CF/EP)laminates have been widely concerned.In this work,the needle-like y-FeOOH nanoparticles were prepared by liquid phase deposition-air oxidation method,and then were calcined under different conditions to obtainγ-FeOOH and y-Fe2O3 hybrid nanoparticles(y-FeOOH@Fe2O3).Effect of calcination condition of y-FeOOH@-Fe2O3 and magnetic field assistance on fracture toughness(Kic)of EP was systematically investigated.Then the selected y-FeOOH@Fe2O3 with the best toughening effect were used to improve the mode I interlaminar fracture toughness(GIc)of CF/EP laminate.The resulting y-FeOOH@Fe2O3 have a length of around 1 μm,a diameter of around 100 nm and the Ms of 8.99-45.96 emu/g.After calcinated at 250℃for 1 h,the γ-FeOOH@Fe2O3 con-taining 24 wt％FeOOH and 76 wt％Fe2O3 achieved the best toughening effect.Under a magnetic field of 0.09 T,the KIC of the y-FeOOH@Fe2O3/EP composite(2.45 MPa m1/2)is 81.7％and 66.7％higher than that of neat epoxy and the composite without magnetic field induction,respectively.Furthermore,the GIc of the y-FeOOH@Fe2O3/CF/EP composite(0.914 kJ/m2)is also significantly increased by 88.8％and 51.8％compared to that of CF/EP and the corresponding composite without magnetic field induction,respectively.
