EVALUATION OF THE ENERGY CONSUMPTION OF MICRONIZAÇÃO OF VEGETAL FIBRES FOR TECHNOLOGICAL APPLICATIONS IN

Resumen

This work presents the study of the consumption of energy for the coconut fibers milling objectifying the technological

innovation for the formation of polymer composites for applications in engineering. Vegetal fibers have an excellent

alternative of technological exploration, for being abundant in tropical countries, presenting low cost and to allow to form

materials with properties of high performance to the consuming and low density. However the formation of composites with

fibers natural can present heterogeneous due to the irregular sizes of fibers. For that is important to establish a technology

that can transform more homogeneous vegetal fibers into its size, making a homogeneous product and that it values the

excellent properties of these materials. The milling of vegetal fibers is one simple technique that allows to transform the form

and the irregular size of prolongated vegetal fibers into very regular spherical forms. This unitary operation of milling will go

to make possible to explore staple fibers vegetal how much the excellent of its properties, as much for the homogeneity of

the sizes of particle how much for the increase of the contact areas. The results had presented the temperatures for the

drying and posterior milling of natural fibers in mill of balls. This work at least established the necessary consumption of

energy for the drying and milling for one hour of coconut fibers with 150 mesh.
