Quantitative Analysis of Hollow Lumen in Jute

In the era of smart materials the natural fiber composites has been of extreme importance. Nevertheless, most natural fiber contains some empty spaces known as lumen or lacuna, which never contribute to the mechanical properties and remain as it is inside the composites. As processing techniques of NFRP composite fabrication varies the properties of composites so this restricts its application. In this research work, initiative has been taken for quantitative analysis of the hollow lumens so that they could be considered in the composite manufacturing process. For doing this, hollow lumen of Bangla white grade B (BWB) jute was analyzed with the help of scanning electron microscopy along with image processing software. Experimental results revealed that proper analysis of the hollow lumens and their consideration can effectively reduce the percentage error of the tensile strength and stiffness values of natural fibers.
