MECHANICAL PROPERTIES AND THE RADAR ABSORBING PROPERTY OF CARBON NANOTUBES REINFORCED ABS COMPOSITE

Carbon nanotubes (CNTs) were prepared by the catalytic floating method in a vertical furnace. They were compounded with acrylonitrile-butadiene-styrene (ABS) after surface treatment. The tensile strength and modulus of the CNTs/ABS composite had increased greatly, but the impact strength had decreased for addition of CNTs. The tensile strength increased from 45.00 MPa to 69.96 MPa, modulus from 0.75 GPa to 1.93 GPa when the content of CNTs in composite increased from 0 wt% to 12 wt%. The radar absorbing property of the CNTs/ABS composite was also studied, and it was found that the composite material exhibited the radar absorbing property in some band range.
