    摘要： A carcass reinforcement for a tire which is intended to bear heavy loads, comprising a composite fabric which comprises a rubber composition of reduced hysteresis and metal cables reinforcing the composition. The elastomeric matrix thereof comprises natural rubber or a synthetic polyisoprene in a majority proportion, and a reinforcing filler comprising a carbon black which meets all of the following conditions: (i) 45≦CTAB specific surface area in m2/g (in accordance with Standard ASTM D3765-80)≦70, (ii) 45≦BET specific surface area in m2/g (in accordance with Standard ASTM D4820-93)≦70, (iii) 45≦iodine adsorption index IA in mg/g (in accordance with Standard ASTM D1510-81)≦70, (iv) ratio (BET surface area/index IA)≦1.07, (v) 115≦DBP structure value in ml/100 g (in accordance with Standard ASTM D2414-93)≦170, (vi) 85 nm≦Stokes diameter dst in nm≦145, where dst is the diameter of aggregates corresponding to the maximum frequency of the Stokes diameters in a distribution of aggregates, and (vii) D50/dst≧0.0090. CTAB+0.19, where D50 is the difference, in the distribution of aggregates, between the Stokes diameters of two aggregates corresponding to one and the same frequency equal to 50% of the maximum frequency of the Stokes diameters, dst and D50 being measured by centrifugal photosedimentometry.

    摘要： Tire component which is not in contact with air or with an inflation gas, comprising a rubber composition based on (a) an elastomeric matrix based on natural rubber, (b) a reinforcing filler, (c) from more than 2.5 to 8.5 phr of sulphur and (d) a dihydrazide compound corresponding to the following formula: in which R is a divalent hydrocarbon radical chosen from substituted or unsubstituted aromatic radicals having 6 to 20 carbon atoms, linear or branched, saturated or unsaturated, aliphatic radicals having 2 to 20 carbon atoms, and n is equal to 0 or 1. These tire components are more particularly those which comprise thread-like reinforcing elements, more especially metallic thread-like reinforcing elements, such as the carcass or crown plies of the tire.
