Abstract

Graphene nanoplatelets (GNPs) are novel nanofillers holding attractive characteristics, including vigorous compatibility with majority polymers, outstanding mechanical, thermal, and electrical properties. In this study, the outstanding GNPs filler was reinforced to the epoxy matrix and carbon fabric/epoxy hybrid composite slabs to enrich their mechanical properties. Graphene nanoplatelets of 0.5, 1, 1.5 and 2 weight percentages were integrated into the epoxy and the physico-mechanical (microstructure, density, tensile, flexural and impact strength) properties were investigated. Furthermore, the mechanical properties of unfilled and 1 wt% GNPs filled carbon fabric/epoxy hybrid composite slabs were investigated. Subsequently, noteworthy improvement in the mechanical properties was conquered for the carbon fabric/epoxy hybrid composites.

石墨烯对碳-环氧复合材料力学性能的增强作用
石墨烯纳米片(GNP)是一种新型的纳米填料,具有吸引人的特性,包括与大多数聚合物的强烈兼容性、优异的机械、热和电学性能。在本研究中,将杰出的GNPs填料增强到环氧树脂基体和碳纤维织物/环氧树脂混合复合板上,以丰富其力学性能。将0.5、1、1.5和2重量百分比的石墨烯纳米片整合到环氧树脂中,并研究了其物理力学(微观结构、密度、拉伸、弯曲和冲击强度)性能。此外,还研究了未填充和1wt%GNP填充的碳纤维织物/环氧杂化复合材料板的力学性能。随后,碳织物/环氧树脂杂化复合材料的力学性能得到了显著改善。
