Vegetal fibers in polymeric composites: a review

et al. 2015

RbstractThe need to develop and commercialize materials containing vegetal fibers has grown in order to reduce environmental impact and reach sustainability. Large amounts of lignocellulosic materials are generated around the world from several human activities. The lignocellulosic materials are composed of cellulose, hemicellulose, lignin, extractives and ashes. Recently these constituents have been used in different applications; in particular, cellulose has been the subject of numerous works on the development of composite materials reinforced with natural fibers. Many studies have led to composite materials reinforced with fibers to improve the mechanical, physical, and thermal properties. Furthermore, lignocellulosic materials have been treated to apply in innovative solutions for efficient and sustainable systems. This paper aims to review the lignocellulosic fibers characteristics, as well as to present their applications as reinforcement in composites of different polymeric matrices.

“…In addition to being a good economic practice, the use of natural fibers can also reduce the use of products are difficult to decompose 2,3 . The use of vegetable fibers as a reinforcement in composite materials boasts a number of advantages: a great potential to improve the performance of the polymers in technological applications 4,5 , a lessening of the environmental impact of its production 6 , relatively low costs, the abundance of such fibers, and the potential biodegradability under suitable environmental conditions 4,5 .…”

Behavior in simulated soil of recycled expanded polystyrene/waste cotton composites

et al. 2013

Composites consisting of waste cotton yarn (CF) from the textile industry and postconsumer expanded polystyrene (EPS) was followed during 90 days of exposure in simulated soil. The mechanical properties, morphologies and chemical natures of the composites were determined before and after exposure in simulated soil. The composites were made using a single-screw extrusion, a twin-screw extrusion and injection molding. The composites showed an increase of the mechanical properties nearly 50% in relation to the recycled expanded polystyrene (rEPS). After exposure in simulated soil the composites presented losses of mechanical properties. Evidence of the oxidation of the samples was demonstrated by the increase in the values of the carbonyl index after 30 days of exposure in simulated soil. Changes in the color of the surface of the sample were observed after 90 days of exposure and are due to the fungi and bacteria colonization on the surface.

“…This finding reveals that even with the inclusion of a reasonable amount by weight of fiber (volume due to the low density of fibers -0.7 g.cm ) in the PP, the resulting composite material remained tough (similar to PP alone) 14,[25][26][27] . These data thus justify the replacement of part of the PP with raw material from renewable natural sources, generating savings compared with pure polymer for a particular component, without losing tensile mechanical properties.…”

The Recycling of Sugarcane Fiber/Polypropylene Composites

et al. 2015

View full text Add to dashboard Cite

Mechanical recycling is utilized to reuse waste and obtain other plastic products via the reprocessing of a material in industrial equipment. Natural fiber composites have become more popular in recent years; however, these composites' mechanical behavior remains less well-understood than single polymers' behavior after recycling. Therefore, the objective of this work was to study the degradation of different sugarcane fibers/polypropylene composites using new grinding and injection processes and to evaluate the mechanical properties of these materials using analysis of variance (ANOVA). This work reveals the mechanical behaviors of recycled natural fiber composites that contain thermal stabilizer additives. Polypropylene composites reinforced with differently treated bagasse and straw fibers (10 and 20 wt%/PP) were obtained through melt mixing using a high-intensity thermokinetic mixer and were subsequently injected. The recycled composites exhibited decreased tensile strength relative to the original composites. However, when thermal stabilizers were added, the mechanical properties were maintained or increased, depending on the fiber and additive types.
