摘要：

The effect of multiwalled carbon nanotubes (MWCNTs) on the properties of wound organic-fiber-reinforced plastics (OFRPs) based on an epoxy matrix modified with a 20% polysulfone has been investigated. It is shown that polysulfone and a polysulfone-MWCNT blend do not affect the density and porosity of the composites obtained. The use of small additions (to 0.3%) of MWCNTs increased the strength and fracture energy of OFRPs in shear. The introduction of 0.1-1.0 wt.% nanotubes into the epoxypolysulfone matrix did not increase the fracture toughness of the composites.
