Abstract :
[en] This work investigates the effect of multiwall carbon nanotubes
(MWCNTs) on the mechanical and tribological behavior of a fiber reinforced
composite (FRC). Fiber reinforced composites and nano-engineered FRCs are
manufactured by resin transfer molding. In-plane tensile tests, in-plane shear tests
and through-thickness compression tests are used to assess the influence of
MWCNTs on the material mechanical behavior. Pin on disk dry sliding tests are
used to quantify the effect of MWCNTs on the friction coefficient and the specific
wear rate. It was determined that (1) MWCNTs have an influence on the
improvement on both the through-thickness compression strength and the specific
wear rate, and (2) they do not influence the material stiffness, in-plane tensile and
shear strengths and the friction coefficient. It is assumed that the observed
improvements are due to the demonstrated positive influence of the MWCNTs
effect on the matrix/reinforcement interfacial strength and on the matrix fracture
toughness.
