Hybridization effect on the mechanical and dynamic mechanical properties of curaua composites

Influence of Stacking Sequence on the Mechanical and Dynamic Mechanical Properties of Cotton/Glass Fiber Reinforced Polyester Composites

“…As temperature, and consequently, mobility of the polymer chains increased 7 , modulus decreased, especially past the glass transition region. For the laminates, this reduction in modulus was less pronounced compared to the resin due to the effect of the reinforcement in the polymer matrix 19 .…”

“…Similar results have . Also, the higher modulus of the glass fiber 20 and its stronger adhesion with the polymer 7 , compared with cotton, lead to a greater increased in stiffness in the glassy region, for a higher glass fiber content in the laminate. This effect was more pronounced for those samples containing glass mats positioned on the ends.…”

“…For composites, DMA has been applied to understand the storage and loss moduli variation upon fiber incorporation. The glass transition temperature and the effectiveness C coefficient can also be estimated 7,8 . The primary goal of this study is to evaluate the effect of the stacking sequence on the mechanical and the dynamic-mechanical properties of cotton/glass fiber reinforced polyester laminates, and to assess the amount of glass fibers that can be replaced without compromising of the evaluated properties.…”

Preparation and characterization of ramie-glass fiber reinforced polymer matrix hybrid composites

“…Finally, the ramie fibers were manually selected to eliminate wastes. The method was adapted by Ornaghi et al 16 studies.…”

“…literature 13 indicates the tensile strength (2000-3500 MPa and 500 MPa) and the Young's modulus (70 and 44 GPa) for E-glass and ramie fibers, respectively. Thus, this increasing is due to the stronger and stiffer characteristics of the glass fiber in comparison with the ramie fiber 25 and also to the better adhesion of the synthetic fiber to the polyester resin in comparison with ramie fiber, with consequently higher degree of stress transfer to the former fibers upon loading 16 .…”
