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 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. Journal of Minerals and Materials Characterization and Engineering,ĪBSTRACT: This study examines the implementation and characterization of a polymer matrix composite material reinforced by sugarcane residues. Implementation and Evaluation of Certain Properties of a Polymer Matrix Composite Material Reinforced by Fibrous Residues of Saccharum officinarum in View of an Applicability OrientationĪUTHORS: Marie Josette Ndengue, Merlin Zacharie Ayissi, Pierre Marcel Anicet Noah, Fabien Betene Ebanda, Atangana AtebaĬomposite, Polymer, Bagasse, Young Modulus, Saccharum officinarum (2011) Effect of Humidity on Mechanical Properties of Flax fibres Reinforced Composites. Higher strength and stiffness obtained for re-dried samples after aging was explained by an increase in crystallinity.Scida, D., Assarar, M., Rezak, A. A parameter is introduced for correlation of normalized stiffness and strength with different aging times and temperatures. In addition to moisture content, aging time was also found to influence the tensile behavior. The reductions in tensile strength and elastic modulus due to water absorption are represented by mathematical relations as a function of moisture content. Kinetics of water absorption and desorption were investigated for polyamide-6.6 composites and Fickian behavior was observed. Four different composites including talc filled and short glass fiber reinforced polypropylene, short glass fiber reinforced polyamide-6.6, and a blend of polyphenylene ether and polystyrene with short glass fibers were used for the study. © 2010 Society of Plastics EngineersĪn experimental study was conducted to investigate the effect of temperature, moisture, and hygro-thermal aging on the tensile behavior of thermoplastic composites. Correlations between the dominant failure mechanisms and AE events amplitude for model specimens were established which can be used to monitor the damage growth process in SRPPCs. Both the number of AE events and the shape of the cumulative AE events versus deformation curve depend on the adhesion between phases. The failure behavior of tensile specimens was assessed by the acoustic emission (AE) technique and the typical failure behavior was deduced for the differently consolidated composites. Composite sheets were produced by a film-stacking method and compression molded for constant holding time and at constant pressure but at different processing temperatures to obtain SRPPC sheets with different consolidation quality. As reinforcement woven fabric, whereas as matrix materials α and β crystal forms of isotactic polypropylene (PP) homopolymer and random PP copolymer (with ethylene) were used. In this work, the fracture and failure behavior of self-reinforced polypropylene composites (SRPPC) was studied. This article also includes the effect of carbon nanotubes on the fatigue life of the polymer composites. Loading condition parameters pertain to stress ratio, mean stress, loading condition, multiaxial stress, and testing frequency. Factors triggering such behavior in composite materials include reinforcing substance, matrix material, fiber orientation or stacking sequence, fiber content, testing environment and so on, together with the damage development process at the microscopic level. This review paper highlights various aspects of the cyclic or fatigue behavior in composite materials. In composite materials, conversely, it is a complex process as these materials possess crack-arresting properties. In metals, failure occurs from the commencement of a single crack and then its propagation. Composite materials are different from metals and they show a distinct behavior under fatigue loading. In fatigue testing, depending on the choice of the researchers, materials are loaded till reaching their failure or till reaching a fraction of the total stiffness loss. It refers to the testing of materials for their cyclic behavior. One of the important tests that conventional and composite materials have to undergo is fatigue test. For replacement of regular metals, composites, especially fiber-reinforced polymer composites, have proved to be a suitable alternative. Composite materials have emerged as an effective substitute for conventional materials in various fields of engineering and structural science.
