The aim of this article is to show that natural fibers extracted from the coconut mesocarp and Tucumã bark can be used as reinforcement for the Bakelite matrix, being a replacement for synthetic fibers. The fruits were submitted to a manual process to extract the fibers, then they were added with percentages of 0.01%, 0.015% and 0.02% in (0.1%) Bakelite for the composites production, by a metallographic mounting press, followed by tests of hardness, accelerated aging and chemical characterization, where they obtained results of hardness of the composite with coconut fiber in 0.01% - 79.3 HRB, 0.015% - 77.9 HRB, 0 , 02% - 20.9 HRB, of the composite with Tucumã fiber in 0.01% - 72.1 HRB, 0.015% - 83.7%, 0.02% - 85% and that the sample without fiber had a hardness of 93 HRB. After the accelerated aging test, it was evidenced that there was no significant deterioration of the samples. In the chemical characterization, the moisture contents of the coconut was 11% and the Tucumã had 28%, the extractives were 36% and 17 and ash contents of 0,16% and 0,78%, respectively. Thus it was concluded that it can be used in areas of thermal and acoustic protection and even open a new window for further research
