Title:
MEASUREMENT SAMPLE AND MEASUREMENT METHOD FOR TENSILE STRENGTH OF INTERFACE SURFACE BETWEEN EPOXY COMPOSITE MATERIAL AND ALUMINIUM
Document Type and Number:
WIPO Patent Application WO/2023/098141
Kind Code:
A1
Abstract:
A measurement sample and a measurement method for the tensile strength of an interface surface between epoxy composite material and aluminum. The measurement sample comprises an epoxy composite material structural member (3), a first aluminum structural member (1), and a second aluminum structural member (2), wherein the epoxy composite material structural member (3) is in casting connection with the first aluminum structural member (1), and is in casting connection with the second aluminum structural member (2), and the surface area of the connection between the first aluminum structural member (1) and the epoxy composite material structural member (3) is greater than the surface area of the connection between the second aluminum structural member (2) and the epoxy composite structural member (3); a first connecting structure is arranged on the first aluminum structural member (1), and a second connecting structure is arranged on the second aluminum structural member (2). The connection between the first aluminum structural member (1) and the epoxy composite structural member (3) and between the second aluminum structural member (2) and the epoxy composite structural member (3) simulate connection modes between an epoxy composite material and aluminum, facilitating tension transmission. In addition, the interface surface between the second aluminum structural member (2) and the epoxy composite material structural member (3) is first to break, improving the accuracy of the measurement results, and providing a new way of testing to ensure the overall performance of a GIS/GIL insulating member.
