Simply flanking the piezoelectric layer with thin concentric layers of metal would not work because metals tend to have a lowviscosity.
仅仅在两侧安放压电层和薄薄的同心金属层是起不了多大作用的,因为金属的粘度很低。

HCH-201 unsaturated polyester resin is designed for centrifugal casting molding glass pipe (HOBAS pipe) design of the structure layer resin is a lowviscosity, medium reactivity of o-benzene resin.
The spherulitic diameter varies markedly in the interface. During mold filling process, the flow layer should be divided to two layers:high viscosity molten layer and lowviscosity molten layer.
