Mechanical Properties Evaluation of Sugarcane Bagasse-Glass/ Polyester Composites

ABSTRACT

A study on tensile, flexural and interlaminar shear properties of sugarcane bagasse (SCB)-glass (G)/polyester hybrid composites is presented. The effects of the relative fibers content and plies stacking sequence on the mechanical properties of hybrid composites were investigated. Morphological studies of the fractured surfaces were performed using scanning electron microscopy (SEM). Results indicated that, the mechanical properties of SCB/polyester composite can be effectively improved by the incorporation of G-fiber through the formation of hybrid composites. Also, with the proper selection of f relative fibers content and plies stacking sequence, the fabricated hybrids can achieve property profiles close to those of homogeneous glass-reinforced composite in terms of specific properties.

摘要

研究了甘蔗渣（SCB）-玻璃（G）/聚酯混杂复合材料的拉伸、弯曲和层间剪切性能. 研究了相对纤维含量和铺层顺序对混杂复合材料力学性能的影响. 用扫描电子显微镜（SEM）对断裂表面进行了形态学研究. 结果表明，通过形成混杂复合材料，加入G纤维可以有效地改善SBC/聚酯复合材料的力学性能. 同时，通过适当选择f的相对纤维含量和铺层顺序，制备出的复合材料的性能曲线与均匀玻璃纤维增强复合材料的性能曲线接近.
