Laminated Composite of Sisal and Curaua Fibers to Different Settings for Use in Bumper Cars 2013-36-0603

The use of composite materials reinforced with natural fibers has been widely studied in recent research seen the availability of feedstock and mainly because the productions facility, low cost and because they are biodegradable. In order to expand the applications of composite materials, this paper proposed to develop hybrid laminar composites associating natural fibers as jute, sisal and curaua in an array of type resin polyester and compare them with commercial bumpers available on the market. The sisal and curaua fibers were manually cut into lengths of 50 mm and then were arranged and incorporated separately with the polyester resin and the jute fiber cut, as a blanket in length 400 × 400 mm2 adopting for that a simple and manual manufacture process. Finally, it was executed a tensile test in hybrid laminated, and then a comparative study of tensile properties of different laminated hybrid composites, jute-sisal, jute-curaua and between the results of the commercial bumpers. The results showed the sisal-jute composite was better because this hybrid laminated had more satisfactory tensile strength and elongation than others.
