【摘要】 复合材料储氢瓶在生产与服役过程中，碳纤维缠绕层会出现空隙和脱黏现象，造成缠绕层分层，气瓶的服役温度会对缠绕层分层扩展产生影响，因此有必要研究温度对于分层破坏行为的影响。在储氢瓶-40～85℃的服役温度范围内设置六个温度点(-40、-20、0、25、50、85℃)，分别进行Ⅰ型和Ⅱ型层间断裂试验。分析了温度对层合板分层性能的影响，研究发现，随着温度的升高，Ⅰ型断裂韧性逐渐提高，Ⅱ型断裂韧性逐渐降低。基于ABAQUS有限元平台，利用内聚力模型，使用试验得到的Ⅰ型和Ⅱ型断裂韧性数据，建立了考虑温度的含初始分层缺陷层合板压缩和拉伸模型。结果表明，温度对于含初始分层区域的层合板压缩性能的影响较大，对于拉伸性能基本无影响更多还原

【Abstract】 During the production and service of the composite hydrogen storage cylinder, the winding layer of carbon fiber will appear voidage and debonding phenomenon, resulting in the lamination of the winding layer. The service temperature of the cylinder will affect the lamination expansion of the winding layer, so it is necessary to study the effect of temperature on the delamination failure behavior. Six temperature points(-40,-20, 0, 25, 50, 85 ℃) were set in the service temperature range of hydrogen storage bottle, and type Ⅰ and type Ⅱ interlayer fracture tests were carried out respectively. The influence of temperature on the lamination performance of laminates was analyzed. It is found that with the increase of temperature, the type Ⅰ fracture toughness gradually increases, and the type Ⅱ fracture toughness gradually decreases. Based on the ABAQUS finite element platform, a compression and tensile model of laminates with initial lamination defects was established considering temperature by using the cohesion model and the type Ⅰ and type Ⅱ fracture toughness data obtained from the test. The results show that temperature has a greater effect on the compression properties of laminates with initial lamination regions, but has little effect on the tensile properties.更多还原
