摘　　要：针对碳纤维全缠绕塑料内衬气瓶检测的需求,提出了一种光纤光栅传感器植入复合材料气瓶的方法,将碳纤维带和凯夫拉材料补强包裹的光纤顺着纤维方向随着碳纤维一起缠绕,最后固化。开设了12根光纤光栅应变传感器通道植入复合材料气瓶的试验,其中10只传感器在复合材料气瓶固化后保持存活,实现了复合材料气瓶固化、水压试验过程中的应变检测。试验结果验证了光纤光栅传感器植入复合材料Ⅳ型气瓶进行应变检测的可行性。For the needs of plastic liner carbon fiber fully wound gas cylinder testing,a fiber grating sensor implanted in composite gas cylinders is proposed,the carbon fiber tape and Kevlar material reinforcement wrapped optical fiber along with the carbon fiber winding in the direction of the fiber,and finally curing.Opened 12 fiber grating strain sensor channel implanted composite gas cylinder test,of which 10 sensors in the composite gas cylinder after curing to keep alive,to achieve the composite gas cylinder curing,hydrostatic test process of strain detection.The results show that the feasibility of implanting fiber grating sensors into composite type IV cylinders for strain detection is verified.
