Desenvolvimento do compósito poliéster/juta: um estudo comparativo.

Abstract

In the present work a polyester based composite with juta reinforcement was developed. The effects of diferent methods of reinforcement treatment on the composites' statical mechanical properties were investigated. The results showed that sodium hypochlorite treatment, in general, caused a decrease on the composites' properties, possibly due to fiber degradation. Silane coupling wasn't efficient, which could be atributed to an incompatibility between fiber/silane agent or the nonreaction of the silane with hidroxyl groups of the celulosic reinforcement.
