Elaboration et caractérisation d’un matériau biocomposite

Abstract

Composite materials are increasingly used in civil engineering for their many advantages, including lightness, strength and durability. They are used in a variety of applications, from structural elements to flooring and the rehabilitation of old buildings. To protect the environment and enhance plant resources, an experimental study on the implementation and characterization of innovative materials is conducted as part of this work. The material developed is a biocomposite based on epoxy resin reinforced with date pits fillers treated with acetic anhydride, with two different sizes: 250μm and 180μm. Each size is used at five different percentages: 5phr, 7phr, 10phr, 15phr, and 20phr. The characterization used include physical tests such as density and water absorption, and mechanical tests such as tensile testing, Charpy impact testing, and micro hardness testing. The results obtained contribute to a better understanding of the physico-mechanical properties of the biocomposite based on epoxy resin reinforced with date pits fillers. The results show improved fillermatrix interfacial adhesion and increased hardness and stiffness of the biocomposites. These materials can therefore be used in civil engineering. This research opens promising prospects for the development and application of sustainable and environmentally friendly composite materials in various industries.
