Publication number: 20230355285Abstract: A method is disclosed for manufacturing a fiber-reinforced implant structure. A fiber-reinforced rigid insert is provided, comprising continuous fibers impregnated with a first thermoplastic polymer. A molding cycle is performed by overmolding. The insert is placed into a mold cavity; and a second thermoplastic polymer in melted form is injection or compression molded into the mold cavity. The insert is thus at least partly covered by the second thermoplastic polymer. The second thermoplastic polymer injection or compression in the mold cavity is cooled, thereby obtaining a molded fiber-reinforced implant structure containing the at least partly covered insert. The insert is in a predefined location in the mold cavity during said injection or compression molding and during said cooling. The first thermoplastic polymer and the second thermoplastic polymer are the same or different. Also disclosed is an implant structure, and an implant comprising said implant structure.Type: ApplicationFiled: April 22, 2020Publication date: November 9, 2023Inventors: Mikko HUTTUNEN, Harri HEINO, Miika LEHTOLA, Ville ELLÄ, Mika LAAKKONEN
