摘要
本文对不同铺设角[+θ_6/-θ_6]碳纤维/环氧树脂复合层板进行了断裂韧性 G的测试,井用扫描电镜对脱层破坏后的微观断口形貌进行了观察。通过研究,将层板的微观破坏机制同宏观力学性能相联系,讨论了其内在规律,并探讨了提高层板断裂韧性 G_c 的有效途径。
In this paper,+θ_6/-θ_6 interlaminar fracture toughness of the carbon/epoxy composite laminates have been determined,The microscopic frac-ture surface of delamination have been observed with the scanning electronmicroscope.By means of these studies,the relationship between the fracturemicromechanism and their mechanics property has been found,and theway of increase fracture toughness of composite laminates has beenapproached,
