Abstract: Carbon nanotubes (CNTs) were directly and uniformly deposited on Ni foam by a simple chemical vapor deposition (CVD) method, and then the selected epoxy resin system was induced into Ni foam supported CNTs to prepare Ni foam/epoxy resin composites modified with CNTs by vacuum infusion molding process (VIMP). Surface morphology of Ni foam and morphology, structure and graphitization of as-formed CNTs were characterized by FE-SEM, TEM and Raman at different reaction temperatures. Meanwhile, the effect of CNTs on damping properties of composites was investigated by dynamic mechanical analysis (DMA). The results show that the CNTs with uniform diameter, high graphitization and purity can be well deposited on Ni foam at 680 ℃. Compared with Ni foam/epoxy resin composites modified without CNTs, the maximum loss factor tan δ _max of Ni foam/epoxy resin composites modified with CNTs increases from 0.69 to 0.78, the glass transition temperature T_g shifts from 60℃ to 68℃, the effective damping temperature range ΔT extends from 39℃ to 44℃, and the damping property increases by 18.9%.
