5 MECHANICAL PROPERTIES OF FILLED RUBBERS 8.5.1 Mechanical Properties in Green State [Pg.402]

The increased lifetime expected from reinforcement by particulate fillers naturally refers to cured pieces. The incorporation of reinforcing fillers greatly [Pg.402]

It is generally reported that elastomers filled with a volume fraction 4 present a viscosity following (Guth and Gold, 1938) [Pg.403]

Elastomer interaction with carbon black or silica is very difficult to estimate and correct. On the other hand, it is much easier to take into account the actual volume of aggregate in the mix, and it has been proposed that a corrected volume fraction 4 c be used, which integrates the influence of filler stmcture as represented by DBF (Medalia, 1974 Kraus, 1970 Medalia, 1973). [Pg.403]

The (pc value represents the actual size of filler aggregates in the mix it includes, naturally, the filler object itself plus a significant volume of polymer that is shielded from deformation by aggregate tortuosity. This part of the polymer that will not be deformed is usually called occluded rubber (Kraus, 1970 Medalia, 1970 1974). [Pg.403]
