Abstract:
In order to obtain new materials, man began to combine different types of materials, thus creating composites. These can not only have properties and costs more attractive than conventional materials, but also generate environmental benefits such as minimizing the consumption of natural resources and taking advantage of waste that would once have been discarded. In this sense, this work aims to characterize the linear thermal expansion of composites reinforced with coconut shell particles in two configurations, processed and unprocessed. The processed particles were ground for 24 hours in a ball mill of the brand Servitech, model CT-240 / A. The tests were performed on a Netzsch dilatometer, model DIL 402 PC, at a rate of 2°C/min, aiming to characterize the behavior of 30 to 190°C. Through the tests it was possible to characterize the behavior of the composites, as well as to observe what the behavior of the composites varied according to the amount of load, in a non-proportional way, and type of load. It is also added that the processing of particulates favors the reduction of internal stresses, influencing less than unprocessed particles in the expansion of the epoxy.
