Abstract
This study examines the implementation and characterization of a polymer matrix composite material reinforced by sugarcane residues. The aim of the study is to enhance the abundantly produced sugarcane bagasse in the form of residues in the processing plants of said sugar cane. The composite material developed takes into account the size parameters and mass load rate of the reinforcement, the variations of which are between 2.5 mm and 4 mm respectively for the first parameter and 10% to 25% for the second. The load on the test tube during the test has a random orientation. The composite is polyester matrix. The cold compression moulding technique was used in the production of the various samples. Physical properties such as the rate of water absorption and the density of the composite are assessed. The three-point bending tests are carried out with the aim of inducing Young’s modulus from the elaborate samples. Analysis of physical properties shows that water absorption increases with the rate of residue load. The average water absorption rate of bagasse fibres is estimated at 8% for the 2.5 mm fiber size and 12% for the 4 mm fiber size for all composites. Mechanical characterization by bending tests reveals a fragile behavior of the samples tested. Young’s modulus decreases when the load rate of fibrous residues increases regardless of the size of the fibers.
Highlights
Natural fibre composite materials have many advantages due to their availability, relatively low cost and low density
This study examines the implementation and characterization of a polymer matrix composite material reinforced by sugarcane residues
The purpose of the experiment is the physical characterization of the composite in order to evaluate the water absorption capabilities as well as the density of the samples, which is followed by mechanical characterization in three-point bending in order to determine the mechanical resistance of the material
Summary
Natural fibre composite materials have many advantages due to their availability, relatively low cost and low density. The mechanical holding of a composite depends on the intrinsic properties of its constituents, on the quality of the adhesion between the matrix and the reinforcement, and on the dispersion of the reinforcement in the matrix [1]. This type of composite has a natural origin and benefits from the many advantages offered by industrial products of organic origin. If synthetic fibres have positives, it is the case that natural fibres mark undeniable points from an environmental point. Fibre from sugar cane may be associated with these considerations
