纤维缠绕玻璃钢容器封头型式的一种。绕丝头每回转一次,缠绕在封头上纤维处于一个倾斜平面里,该平面与封头曲面的交线即为平面缠绕封头的纤维路经。当极半径与等张力封头的极孔半径相同时,平面封头曲线与等张力封头曲线几乎相同。平面封头上的纤维张力是变化的,不是一个常值。适用于极孔不等的容器。 Filament winding FRP container head type a. Winding head per revolution, wrapped in the head on the fiber in an inclined plane, the plane and the surface of the head of the intersection is the plane winding head of the fiber path. When the polar radius is the same as the polar radius of the isotonic head, the plane head curve is nearly the same as the isometric head curve. The fiber tension on a flat head is variable, not a constant value. Suitable for containers with different polar holes.
