Abstract:Epoxy resin/MWCNTs/HGMs syntactic foams were fabricated by using ultrasonic dispersion and die casting method.The effects of content of MWCNTs on density,compressive strength and water absorption of syntactic foam were studied.The results show that when the volume of HGMs is 60％,with the increase of the content of MWCNTs,the compressive strength increases first and then decreases.When the content of MWCNTs is 0.1％,the maximum compressive strength is 44.03 MPa,the density of syntactic foams is 0.572 g/cm3,and the water absorption rate is under 1.0％.With the increase of the amount of carbon nanotubes,the compressive strength and density of solid buoyancy materials is decreased,and the water absorption is increased.
