Mechanical Properties of Rice Husk /Carbon Black Hybrid Natural Rubber Composite

Abstract

The mechanical and end use properties of natural rubber reinforced rice-husk/Carbon Black hybrid filler, was investigated. Hybrid filler were used to prepare a natural rubber vulcanizate in order to determine testing data for the mechanical properties of the compound. In the sample preparation, six levels of filler loading were designed, which include variation in carbon black volume content.  Tensile strengths, compression set, abrasion resistance, and Hardness, of the vulcanizate shows improvement with increase in carbon black content, while elongation at break shows decrease with increase in carbon black content. The flex fatigue shows great improvement. Thus rice-husk/Carbon Black Hybrid filler can be utilized as reinforcing filler in the rubber industry, where specific end-use property of a rubber product is required.
