Strength Evaluation of Green Composite with Variation in Cross-Sectional Area of Plant-Based Natural Fibers
Nowadays, natural fiber-reinforced green composites are increasingly being used in the industrial field. The strength of natural fibers is often evaluated on the assumption that the fibers’ cross-sectional shape is circle, but this is rather observed as an ellipse. In the present study, therefore, we propose a new method to calculate the cross-sectional area of natural fibers by measuring their projection widths. In addition, we propose a strength distribution function with taking account of variation in cross-sectional area, based on Weibull distribution, and discuss the validity of the proposed distribution function.
