Process of confection of polyamide compounds with natural fibers and compounds of polyamides with natural fibers

Abstract

The present invention relates to a process of production of polyamide compounds with natural fibers and polyamide compounds with natural fibers, establishes the fact of using natural fiber to obtain a compound with mechanical properties close to the one obtained with inorganic loads by means of continuous process with extrusion and molding by injection process; the processes presented allows the obtainment, by means of injection, of finished products with precise dimensional and complex features; the fact that the compound with natural Curauá fiber presenting suitable mechanical properties combined to a lesser density than the compound with inorganic load is interesting to the automotive industry as vehicles manufactured with lighter parts consume less fuel.

1 . A polyamide compound with natural fibers establishes a compound formed by 80 wt % of polyamide and 6 and 20 wt % of Curauá fiber, and having a density of about 1.18 g cm 3 . 
     
     
         2 . A polyamide compound with natural fibers characterized by the fact of having an increase in Young's modulus of 300% under traction and 80% in tension in maximum force. 
     
     
         3 . A polyamide compound with natural fibers characterized by the fact of being applicable in the automobile and civil construction industries.
