研究了富勒烯分散对碳纤维增强环氧基复合材料(CFRPs)力学性能的影响。评估了[0](8)、[90](16)、[45/0/-45/90](2S)层合板的拉伸、压缩、开孔压缩、冲击后压缩、粘结、短梁剪切和层间断裂韧性等力学性能。将0.5%的富勒烯分散到基质树脂中，可使拉伸和压缩强度提高2-12%。此外，复合材料的层间断裂韧性提高了约60%。结果表明，少量富勒烯(0.1-1wt.%)增加了环氧树脂本身的破坏应变，从而提高了CFRP的强度。(C)2009爱思唯尔有限公司。保留所有权利。
This study examined the effect of fullerene dispersion on the mechanical properties of carbon-fiber reinforced epoxy matrix composites (CFRPs). Mechanical properties such as tension, compression, open-hole compression, comparession after impact (CAI), binding, short beam shear, and interlaminar fracture toughness were evaluated for [0](8), [90](16), [45/0/-45/90](2S) laminates. Tension and compression strengths increased 2-12% by dispersing 0.5% of fullerene into the matrix resin. Furthermore, interlaminar fracture toughness of the composite was improved by about 60%. It was revealed that a small amount of fullerene (0.1-1 wt.%) increased the failure strain of epoxy resin itself, thereby improving the CFRP strength. (C) 2009 Elsevier Ltd. All rights reserved.
