Using the curves obtained with a Monsanto oscillating disk rheometer, a clear reaction can be seen between short oxidized carbon Γbres and the epoxidized natural rubber matrix, which does not occur, or occurs to only a very small extent, when non-treated carbon Γbres are used. This reaction causes a continuous, although less accentuated, increase in the elastic component of the S force couples.
The extent of the reaction depends on the Γbre content, on the degree of oxidation of the Γbres and on the temperature. The reaction among the matrix and Γbre components is translated into an increase in the percentage of non-solvent extractable rubber.

The effect of short-carbon fibre on the anisotropy in hysteresis loss and tension set of two thermoplastic elastomers, based on natural rubber, high-density polyethylene blend and styrene-isoprene-styrene block copolymer, were studied. The composites based on natural rubber-high density polyethylene
Stress-strain and stress relaxation properties are studied in composites consisting of a thermoplastic elastomer butadiene styrene copolymer (SBS) matrix and oxidated carbon fiber. The results obtained from samples at different degrees of oxidation are contrasted with those obtained from SBS filled
