| description | This paper summarizes a research aimed to develop a methodology for determining the cross-sectional area of Guadua angustifolia bamboo fibers. The method includes the immersion of fibers into a resin, surface preparation, acquisition, and analysis of optical micrographs using commercial software. Measured areas were compared with other values obtained for thereof, from a standard gravimetric methodology commonly used on natural fibers, which showed substantial differences among calculated areas. Random samples were subjected to both methods using data distribution functions, and the analysis was carried out to determine their statistical goodness. Analysis of fibers diameter distributions reveals they are very well described by a lognormal distribution function. Furthermore, standard gravimetric methods tend to overestimate the fibers’ cross-sectional area in an average value of 15%, which could result in similar magnitude differences on the determination of some mechanical properties such as the tensile strength and the modulus of elasticity. |
