Mechanical Behavior of Thermo-Mechanical Corn Stalk Fibers in High Density Polyethylene Composites
Agricultural waste, made up of corn stalks and leaves, is the second most abundant residue after cereal straw in United Estates. In this paper, thermo-mechanical fibers were produced from corn residues and used as the reinforcing element of high density polyethylene (HDPE). Maleated polyethylene was used as coupling agent. The obtained corn/HDPE composites were mechanically characterized under tension and flexural stress conditions, and the interfacial properties of the composite were studied. The fiber-matrix interface was evaluated considering the compatibility factor of the rule of mixtures and the interfacial shear strength of the composites. Both tensile and flexural properties were modeled, and the intrinsic properties of the reinforcing fiber determined. From the results, the good mechanical performance of HDPE composites reinforced with these thermo-mechanical corn fibers is stated.

- 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.
