Effect of Carbon Black on Dynamic Properties of Rubber Vulcanizates
TL;DR: In this paper, the dynamic properties of rubber vulcanizates with carbon black as a filler are investigated. But the effect of adding carbon black to the rubber is not discussed.
Journal ArticleDOI
Morphology of aggregates: VI. Effective volume of aggregates of carbon black from electron microscopy; Application to vehicle absorption and to die swell of filled rubber
TL;DR: In this paper, the volume of solid in an aggregate is computed from the particle size and projected area (as measured with the electron microscope), with the use of a relation based on floc simulation, and the packing volume of an aggregate at the end point is taken heuristically as equivalent to that of a sphere of the same projected area.
Journal ArticleDOI
Morphology of aggregates
TL;DR: In this article, the silhouette of an aggregate is treated as a plane figure, for which are calculated the radii of gyration about the two central principal axes in the plane, and other parameters are also calculated including the area and bulkiness, as well as a "structure factor" which expresses the excess area swept out by the figure as it rotates.
Journal ArticleDOI
Morphology of aggregates—II. Size and shape factors of carbon black aggregates from electron microscopy
Avrom I. Medalia,F.A. Heckman +1 more
TL;DR: In this paper, the authors measured the size, anisometry and bulk size of carbon black primary aggregates by electron microscopy and calculated the weight-average parameters with the aid of a relation between projected area and number of particles per aggregate, based on computer simulated flocs.
Journal ArticleDOI
Filler Aggregates and Their Effect on Reinforcement
TL;DR: The most highly reinforcing fillers, namely carbon blacks and silicas, consist of aggregates of quasi-spherical particles fused together as discussed by the authors, and they can be used to reinforce fillers.
