Abstract: The
viscoelastic properties of the normal PTFE plastic and
strengthened PTFE plastic for bearing pad are measured. The
mechanical properties of the composite material for bearing pad,
which is made of the aforementioned plastics as matrix
reinforced by fine bronze elastic springs, are modeled and
relaxation modulus of the material are presented. The difference
between these two kinds of PTFE is studied. The results show
that the complex modulus of PTFE plastics for bearing pad is
higher than that of normal PTFE plastics.
Key words:
