【摘要】 碳纤维全缠绕气瓶作为储氢容器已经取得了长足的发展,然而钛合金内胆碳纤维全缠绕压力容器作为潜艇配备的气瓶,需要考虑深海环境带来的更多极端条件的挑战。这些挑战包括碳纤维全缠绕气瓶本身的制造缺陷不可避免,在海水腐蚀和压力循环作用下,又可能萌生新的缺陷,缺陷对复合材料力学性能的影响难以评估,长周期运行过程中更缺乏有效的检测评价手段。本文总结了课题组近年来在气瓶细观缺陷多尺度力学建模、缺陷的随机分布和缺陷响应预测、以及光学无损检测等方面取得的进展,指出了未来的研究方向。更多还原

【Abstract】 Carbon fiber overwrapped composite cylinders have made great progress as hydrogen storages,but titanium alloy liner carbon fiber overwound pressure vessels equipped with submarines need to consider the challenges of extreme conditions brought by the deep-sea environment.These challenges include the inevitable manufacturing defects of cylinders,the possibility of new defects under the corrosion of seawater and pressure circulations,the difficulty in evaluating the impact of defects on the mechanical properties of composite materials,and the lack of effective detection and evaluation methods in the process of long-term service.This paper summarizes the progress made by the research group in the multi-scale mechanical modeling,random distribution of defects and their response prediction,also the optical nondestructive testing methods in recent years,and points out the future research directions.更多还原
