Effect of the Varying Percentage Diss Fiber on Mechanical Behaviour of the Based Polyester Bio-Composite

Abstract

Improving the mechanical and physical properties of bio-composite materials involves the incorporation of plant fibers such as Jute, Hemp, Kenaf, Ramie, Sisal, Linen, etc. The existence of Diss grass (Ampelodesmos mauritanicus) in abundance in the east of Algeria especially in Khenchela region and taking into account their mechanical resistance and their low density, which justifies their choice of use in composite materials. Tensile and hardness tests for different volume fractions (from 05% to 20%) of short fibers of Diss are performed. The increase in fiber content and their treatment improves the mechanical characteristics of the composite materials. These concentration levels are added to a Polyester resin matrix. Our work relates to the study of a composite material reinforced by a vegetable fiber of which different volume ratio of short Diss fiber are considered. The results collected are purely experimental.

Experimental Investigation of Mechanical Behaviour and Damage of Bio-Sourced Sandwich Structures Based on Date Palm Tree Waste and Cork Materials

“…Date palms are thrown away large amount of waste every year, for this we can exploit as composite materials or sandwich structures. Several researchers have studied the mechanical behavior of bio-composites [5][6][7] and of bio-sandwiches [8,9].…”

“…Among the areas of research that have been presented in recent years, a set of research on the development of composite materials by including natural materials in the composition of composites as alternative materials. Several researchers have studied the mechanical behaviour for the improvement of unsaturated polyesters properties of biocomposites [7,11,12], they discussed the possibilities of developing a natural waste, produced from date palm in the northern Algerian Sahara, associated with the polymer matrix of a thermosetting polyester resin. The use of these natural materials can be due to their outstanding mechanical and physical properties, as well as their high availability in nature at low cost and the biodegradability.…”
