摘要
对一碳纤维缠绕压力容器壳体在已知爆破压强为30MPa的情况下,通过理论计算得到缠绕角、筒体螺旋向及环向缠绕厚度及各缠绕层数等工艺参数。按此工艺参数,采用环氧/胺类体系,选取了传统刚性较高的配方制备了5个碳纤维缠绕压力容器壳体试件,按照国家标准GB 15385——2011对试件进行水压爆破试验,获得爆破压强,均值为34.2MPa。最后又利用ANSYS软件对这一模型进行了有限元分析,得爆破压强为32MPa。比较结果显示:纤维缠绕复合材料压力容器的有限元设计与实测的爆破实验结果有较好的接近,使其在工程上的应用具有很好的实用价值和经济价值。
With the condition of blasting pressure known as 30 MPa the winding angle ,cylinder helical ,hoop winding thickness ,twined layers and other process parameters of the carbon fiber twined pressure vessel were calculated .Depending on the process parameters ,taking the epoxy/amine system and selecting the high rigidity of the traditional recipes five pressure vessel specimens of carbon filament wound were manufactured .In accordance with GB 15385 -2011 hydraulic blasting tests of the specimens were carried out .for blasting pressure .The mean of blasting pressure for the specimens was 34 .2MPa .Finally bursting pressure of the specimens was 32MPa by ANSYS finite element analysis . The comparison results show that the finite element design of filament wound composite pressure vessels was closing to blasting experiment results .So finite element design of filament wound composite pressure vessels has good practical and economic value in engineering applications .
