Graphene based nano-reinforcements have emerged as promising fillers in polymeric materials. The objective of the present article is to elucidate the reinforcement effect of graphite oxide nanoplates (GONP) on the thermal, flexural and creep performance of glass fiber/epoxy (GE) composites. Thermal analyses by DSC, DMA and TGA showed reduced glass transition temperature of GE composite due to GONP incorporation, whereas no significant impact has been observed on the decomposition temperature. GONP addition has been found to be beneficial on the flexural properties of GE composite. To understand the effect of temperature on long-term mechanical durability, creep tests have been performed at various temperatures (50, 80 and 110 °C). Further, elevated temperature creep behaviour has been assessed at various stresses (10, 20 and 40 MPa) to comprehend the combined effect of temperature and stress. Improved creep resistance has been observed in GONP modified GE composites at relatively lower temperature and stress.

石墨烯基纳米增强材料已成为聚合物材料中有前途的填料。本文的目的是阐明氧化石墨纳米板（GONP）对玻璃纤维/环氧树脂（GE）复合材料的热，弯曲和蠕变性能的增强作用。通过DSC，DMA和TGA进行的热分析表明，由于掺入了GONP，GE复合材料的玻璃化转变温度降低，但未观察到对分解温度的显着影响。已经发现添加GONP对GE复合材料的弯曲性能是有益的。为了了解温度对长期机械耐久性的影响，已在各种温度（50、80和110°C）下进行了蠕变测试。此外，已经评估了在各种应力​​下的高温蠕变行为（10，20和40 MPa）以了解温度和应力的综合作用。在相对较低的温度和应力下，在GONP改性的GE复合材料中观察到了改善的抗蠕变性。
