Mechanical Properties and
Permeability of Polypropylene and Poly(ethylene terephthalate)
Mixtures
چکیده:
The synthetic membranes currently used for soil
stabilization and road construction are mainly made of
polypropylene and of polyesters. They are used separately for each
application. The polymer used has an effect on the wettability and
the permeability of the membrane. The polypropylene membranes, for
instance, have a zero wettability, whereas it is high for polyester
membranes. This paper reports on the mechanical properties
and the permeability
of mixtures of polypropylene (PP) and poly(ethy1ene terephthalate) (PET). The elastic modulus of the mixture was at a minimum for a 50/50 mixture. For the other compositions, the moduli gave a positive deviation as compared with the additivity equation results. This is probably due to the fact that pure PET has a fragile behavior at the
