| Abstract Scope |
In recent years, the interest of developing composites reinforced with renewable materials has grown tremendously since social requests demands products that cause low environmental impact. Natural lignocellulosic fibers are extensive used as a reinforce for matrix polymeric composites and when compared to inorganic fibers such as carbon and glass, the natural fibers presents low cost, low weight and have higher specific tensile strength and flexural strength. The present work have been dedicate to analyze a scientifically new ligocelluloic fiber for engineering aplications known as seven-islands-sedge in Brazil. Concerning to discover how it behaves in high temperatures the natural fiber was subjected to an differential scanning calorimetry (DSC) analysis , besides composites reinforced with 0, 10, 20 and 30% of volumetric fractions of this fiber were also analysed. A endothermic peak was found on 97.4°C and a Tg peak was observed on 66.8 and 81.1°C for the different conditions of composites. |
