| Abstract Scope |
The fibers extracted from the stem of the sedge (cyperus malaccensis) plant have been investigated as possible composite reinforcement, aiming to discover a possible new fiber for an engineering aplication. For this reason these fibers were incorporated in an epoxy matrix in different volumetric fraction of 10, 20 and 30%v/v and were investigated for mechanical properties associated with tensile strength. Plates were fabricated following the dimensions of 150 x 15 x 2mm as required by ASTM D3039. The statistics analysis of the results were performed by ANOVA and Tukey tests based on a 95% confidence level. Besides, a Weibull analysis was applied and have shown a great confidence of the weibull parameters. Results disclosed a tendency of increasing the mechanical properties with increasing fiber content. Tukey test revealed a significant difference of the 30% condition when compared to 10% condition,an Weibull Analysys have shown better parameters for the 30% condition. |
