Abstract

Rheological tests (torque, melt flow rate, melt viscosity), mechanical tests (tensile strength, elongation at break, impact strength), dc electrical conductivity on ABS copolymer/ stainless steel fibber composites with fibber concentration between 0 and 5% (vol.) are reported. Tensile strength and relative modulus are not affected by the presence of stainless steel fibbers in the range 0…5% (vol.). Elongation and impact strength decrease drastically even at low concentration of fibbers. Low concentrations of metallic fibbers (which are necessary for static dissipative properties) have a little influence on rheological behaviour. A fluidisation trend is observed when stainless steel fibbers are introduced in ABS. Non-linear behaviour is observed at high electrical fields..
