Comparação de propriedades mecânicas dos compósitos reforçados com fibras de juta e de sisal

Abstract

The constant search for technological improvement regarding the use of various types of composite materials to obtain various products on the market means that there are new methods and standards with regard to the study of alternative and sustainable sources for the composition of new materials. Currently, the concept of sustainability is about the point of view of environment protection, and this influences the issue of studying new composites to obtain materials that do not harm nature, a fact that already exists. The global trend is for human beings to start consuming many products that are discarded in a period and there’s no policy aimed at their reuse, in addition to serving as a benefit to society, in view of the inclusion in the job market of people who make a living from recycling materials. Another issue to be raised and it is very pertinent is related to the study of natural fibers that can replace artificial or synthetic fibers, those which are under study so that new composite materials can be manufactured on a large scale. This work aims at comparative study of the mechanical properties of two composites, made with epoxy resin, each one with natural fiber reinforcement, sisal and jute, treated with Sodium Hydroxide (NaOH), for the purpose to obtain better resistance for these materials, giving to them the due importance materials employment, obtaining the mechanical properties value averages for comparison between these materials.
