Abstract
In this paper, 400 flax fibers with 10 different lengths (40 fibers at each
length) are experimentally characterized (quasi-static tensile behavior) and
then the results are statistically analyzed. The quasi-static tensile test results
appeared to have a large dispersion, which makes it possible to measure the
degree of variability in the ultimate tensile strength (UTS), failure strain, and
the Young’s modulus of the fiber, at different gage lengths (10 mm to
500 mm). The variation in mechanical properties at each fiber length is
established using two and three Weibull statistics based on maximum like-
lihood estimation (ML) and least square estimation (LS). Finally, all 10 groups
for each tensile property are analyzed by one-way (ANOVA).
