Evaluation of statistical strength of bamboo fiber and mechanical properties of fiber reinforced green composites

Green composites made from bamboo fibers and biodegradable resins were fabricated with press molding. On the basis of the Weibull distribution and the weakest-link theory, the statistical strength and distribution of bamboo fiber were analyzed, and the tensile strength of green composites was also investigated. The result confirms that the tensile statistical strength of fiber fits well with two-parameter Weibull distribution. In addition, the tensile strength of bamboo fiber reinforced composites is about 330 MPa with the fiber volume fraction of 70%. This value is close to or higher than that of other natural fiber reinforced green composites.
