FRP汽车储气罐缠绕参数对力学性能的影响

Influence of Winding Parameters of FRP Vehicle Air Tanks on Mechanical Properties

在设计商用车所使用的FRP汽车储气罐时,通过选取不同的玻纤缠绕参数、碳纤缠绕参数和胶接接头参数,运用有限元分析探讨缠绕参数与力学性能之间的交互效应,为设计新型FRP汽车储气罐中相关参数的选取提供参考。结果表明:筒身的玻璃纤维以及碳纤维缠绕层数推荐布置为4到6层,纤维的缠绕角以不同的缠绕次序交叉缠绕较佳;胶接接头中胶层厚度增加会减缓胶层损伤,但过厚会使得胶层的刚度下降,胶接长度推荐设置为40 mm。

When designing fiber reinforced polymer(FRP)air tanks for commercial vehicles,different glass fiber winding parameters,carbon fiber winding parameters and glued joint parameters were selected,and the finite element analysis was used to explore the interaction between the winding parameters and mechanical properties.It provides a reference for the selection of relevant parameters in the design of new FRP vehicles air tanks.The results show that the number of winding layers of glass fiber and carbon fiber in the barrel is recommended to be 4-6,and the winding angle of the fiber is better to cross-wind in different winding order.The increase of the thickness of the adhesive layer in the glue joint can reduce the damage of the adhesive layer,but excessive thickness can reduce the rigidity of the adhesive layer.The recommended bonding length is 40 mm.
