Characterization of Aechmea magdalenae Leaf Fiber Yarns
Recognizing the increased attention being given to the renewable resources due to the ecological considerations and extensive research being conducted into properties of plant fibers for the development of composites, this paper presents information on source, extraction and marketing
as well as the physical and thermal characterization and tensile strength properties of Aechmea magdalenae leaf fiber yarn. The diameter and density of the yarns are found to be about 584 ± 32 μm and 1.5 g/cm–3 respectively. The cells in the fiber being elliptical
in shape are arranged in a regular fashion. The crystallinity index of the yarn calculated through X-ray analysis is found to be 55%. Average ultimate tensile strength, Young's modulus and % elongation of yarns are found to be about 2 GPa, 42 GPa and 7.0 respectively. The tensile properties
observed are explained by the fractographic studies carried out with a scanning electron microscope.

- The goal of the creation of a biobased economy is challenging to agriculture, forestry, academia, government and industry. The extractable resources of the Earth are finite, regardless of the quibble over when they will be depleted. The economic, political and social demands for biobased chemicals, materials and energy are expected to radically transform the materials industries, particularly the plastics industry as well as the biofuel industry. These changes will be based on the principles of sustainability, eco-efficiency, industrial ecology, and green chemistry and engineering. In keeping with the growth of knowledge in this field, there is a strong need for a forum to share original research related to biobased materials and bioenergy. The Journal of Biobased Materials and Bioenergy (JBMB) has been created as an international peer-reviewed periodical to fulfill the need for communication in these research areas. This journal will encompass related research activities in all fields of science, engineering and the life sciences.
