Chemical Treatment and Characterization of Fiber of Babassu Coconut Epicarp (Orbignya phalerata) for Application in Polymeric Composite

摘要

This set of mechanical properties of plant fibers allows its use as a reinforcement element in polymeric matrices and composites can be used in various sectors, and thus expanding the scope of use and the aggregate value of plant fibers. In this work, the choice by the use of alkali process to make the treatment of epicarp babassu fibers was decided in view of that it provides an effective, simple and low cost implementation process and also for being the most widely used method for modifying the surface of the fiber forming polymer composites. By SEM, it was observed the removal of wax layers, the impurities on the fiber surface and tyloses. With alkali treatment, it was also possible to notice the narrowing and closing of craters due to the packaging of denser material.
