Viabilidade de substituição da fibra de vidro por fibras naturais ( sisal, juta e coco) na agroindústria nacional.

Abstract

In this work was analyzed the performance of composites reinforced with sisal fiber, jute and coconuts fibers ás changing alternative of composites sampling of fiberglass, actually used in industrial market. All of samples were produced by TRV process (Vácuum Resin Transfering), with and without mineral filler incorporátion in the polyester matrix and its changed from 0% to 30% and of these variables was possible investigated its effects in the composites. After that, by tensile strength, youngªs modulus, strain of rupture, flexurál strength ánd impact strength, have been analyzed the chance to replace the fiberglass like reinforced composites by vegetable fibers, from renewable sources.
