Abstract:
There is a great deal of effort by the academic community to develop new materials with differentiated properties, specifically in multilayer shielding systems. Basically, multilayer shield systems are formed of three layers, such as ceramic inserts, composites reinforced with natural fibers, and, finally, layers of aramid fabric. With this in view, this work investigated the mechanical effects caused by the addition of carbon black in jute fiber reinforced composites. Long-term carbon black is known as a reinforcing agent in tires, while jute fiber reinforced composites have extensive scientific publication in multilayer shield systems, and the combination of these, at least to date, has been poorly investigated . With this in mind, two composites, following the standard D3039 / D3039M-17, were prepared and tested, both composed of 30% by volume of jute fiber and epoxy resin differing only by the doping in one of 5% by volume of Carbon Black. The results obtained in the doped composites presented an improvement equivalent to 15% in the mechanical resistance when compared to its non-doped equivalent. In addition, the carbon black doped composites presented conductive properties, not properly exploited in this work.
