Mechanical Characterization of Composite Materials Matrix Hybrid Polyester Reinforcements Sisal/Glass Jute/Glass

There's an intense growth on the study and development of new materials in recent years, especially in the category of materials that are less harmful to the environment and, moreover, have a low production cost. Following this tendency, composites reinforced with natural fibers that can replace satisfactorily a wide variety of materials have been produced. This work aims to study the properties presented by aplateshaped composite when reinforced by a fiberglass blanket with jute/sisal fibers in different lengths, produced in accordance with ASTM D3039 standard. The composite was produced by hand-lay-up process overlapping jute, sisal and fiberglass layers impregnated with polyester resin, placed in a hydraulic press under a 500 kg load. Specimens in accordance with ASTM D3039 were extracted and tested according to its procedures.
