Abstract :

Accurate determination of mechanical properties plays an important role to comment on improvement in the mechanical properties of particle filled PP fibers. However, the existing standards are not totally suitable for reliable strength determination of particle filled PP fibers. In the framework of this study, microsized talc particle-filled PP fibers were produced with different talc ratio, and tensile strength measurements were preformed with various gage lengths. Statistical Akaike information criterion analysis showed that strength distribution of talc-filled PP fibers is best characterized by Weibull distribution function. It is reported that, the gage length has almost no influence of Weibull parameters of pure PP fibers whilst strong effects on Weibull parameters of talcfilled PP fibers. It is shown that if the tensile strength of talc-filled PP fibers is to be measured, at least 50 samples, which is more than value suggested by existing standard, should be used for a reliable determination of Weibull parameters. Therefore, the main aim of this study is to question the feasibility of minimum sample size suggested by the existing ASTM D3822 standard for reliable strength measurement of talc filled PP fibers.
