Análise de compósitos poliméricos com reforço de agregados

Abstract

This study aimed to evaluate the mechanical and flammability properties of composites of isotactic polypropylene strengthened with additives of manioc remains, sawdust and egg shells. The study included the characterization of isotactic polypropylene and additives, in terms of general characteristics, process of generation and the current destination. For this characterization of isotactic polypropylene and households was conducted, describing the process of how they are generated, the amount generated and their current destination. In addition, flammability and mechanical properties of the composites were evaluated, and, for the tests specimens were prepared, which were based on a mixture of 5 % or 10 % of polypropylene and additives. To evaluate the thermal properties of composites, the flammability test was used with reference to ASTM D 635-10 Norm, and to evaluate the mechanical properties of composites, voltage test was used with reference to ASTM D 638-10 Norm was used. With the characterization of polypropylene and additives, it was found that residues of starch manufacturers have as current destination, animal feeding. In the residues generated in the bakery are discarded as regular waste. Having as destination, the city landfill, and the disposal of waste from the furniture industry is used in aviary and pigs on farms. By performing the flammability test, the composite showed no significant difference, the additives do not interfere with the thermal properties of the composite In voltage test, significant differences occurred; it was observed that the addition of additives reduced the resistance of the composites. It is notorious that the addition of additives to polypropylene can be an alternative for the recycling of waste from starch by industry, furniture industry and bakery remains, thereby, taking advantage of the implicit value that they have and avoiding damage to the environment.
