Abstract
Single fiber tensile tests using two different gripping methods were carried out on various fiber lengths. One method (the glue-tab grip) consists of mounting a fiber onto a rigid tab as specified in ASTM C1557-03 using an adhesive, while the other (the direct grip) involves directly clamping a fiber using PMMA blocks. Based on graphical statistical analyses using kernel density and q-q plots, the tensile moduli obtained by the glue-tab grip as a function of the fiber gauge length are clearly different than those of the direct grip for the fiber length from 2 mm to 10 mm, which is caused by the gripping effect. In addition, the tensile strains and strengths obtained by the glue-tab grip were different than those of the direct grip at the short fiber gauge lengths (i.e. 2 mm to 10 mm). The differences between the tensile properties (i.e. modulus, strain and strength) for the two grips measured with the 60 mm fiber length were not statistically significant compared to the results with the short fiber lengths.Citation
