Experimental analysis of the mechanical properties of hybrid bio-composites

Abstract

Bio-sourced composite materials have become a potential substitute to composite materials with synthetic fibers. Recently, they have used these promising materials of the future, such as automotive, marine, aerospace, consumer sports goods and electronics industries. In Algeria, There is a growing interest in date palm fibers from agricultural waste due to their availability and their physico-mechanical properties. In this experimental study, we attempts to valorized theses fibers. For that an hybrid composites were fabricated by the judicious mixture between natural (short rachis fibers) and synthetic materials (long glass fibers) impregnated in epoxy matrix. The mass fraction (Vm) was maintained at 15%. To predict an adequate mechanical properties several, tensile, bending and Charpy specimens were carried out for three different glass fibers orientations (0◦, 45° and 90◦). The orientation of the fibers of the glass/epoxy layer considerably influences the mechanical properties of hybrid materials.
