Mechanical and Dielectric Strength of Laminated Epoxy Dielectric Graded Materials. [PDF]

Polymers (Basel), 2020
Laminated epoxy dielectric graded material is a commonly used insulating material with broad application prospects in power equipment. The interlaminar interfaces of laminated epoxy dielectric material between different layers form during its lamination process, and these interfaces are the crucial characteristic structures determining the mechanical ...
