Title:
JOINED BODY USING POLYETHER ETHER KETONE RESIN, AND COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2024/095649
Kind Code:
A1
Abstract:
According to the present invention, provided are: a joined body of a PEEK resin and a metallic oxide, the joined body having high bonding strength between the PEEK resin and the metallic oxide and not being prone to interface fracture; and a composite material. This joined body is a joined body (1) obtained by joining a polyether ether ketone resin (2) and a metallic oxide (3). The relative difference between the distance between benzene rings that form molecular chains of the polyether ether ketone resin (2) and the distance between metal atoms that form the crystalline structure of the metallic oxide is 5% or less; and the atom density in a crystal plane of the metallic oxide where the polyether ether ketone resin is joined is at least 17 atom/nm2. This composite material is a composite material that contains a metallic oxide, with a polyether ether ketone resin serving as a matrix. The relative difference between the distance between benzene rings that form molecular chains of the polyether ether ketone resin and the distance between metal atoms that form the crystalline structure of the metallic oxide is 5% or less.
