  • Method for preparing a composite high strength to weight structure with fray resistance
    Patent number: 4128963
    Abstract: A novel structural member, such as a tennis racket frame, having an unusually high strength to weight ratio is provided comprising an expanded foamed plastic core integrally bonded to a shell comprising at least one layer of resin-coated unidirectionally oriented graphite fibers, the shell completely encasing the core at any transverse cross section of the structural member with a veiling strip wrapped around said core beneath the innermost or beyond the outermost of the graphite fiber layers, or both.
    Type: Grant
    Filed: November 25, 1977
    Date of Patent: December 12, 1978
    Assignee: Fansteel, Inc.
    Inventor: Pol Dano
  • Method for preparing a composite high strength to weight structure having shell and sleeved core
    Patent number: 4129634
    Abstract: A novel structural member, such as a tennis racket frame, having an unusually high strength to weight ratio is provided comprising an expanded foamed plastic core integrally bonded to a shell comprising at least one layer of resin-coated unidirectionally oriented graphite fibers, the shell completely encasing the core at any transverse cross section of the structural member, with a seamless sleeve made of a thin, flexible cellulosic film between the core and the shell.The structural member is prepared by arranging within a mold cavity an outer shell comprising at least one sheet of resin-coated unidirectionally oriented graphite fibers and a core comprising a foamable resin composition while the core is maintained within a seamless sleeve made of a thin, flexible cellulosic film, sealing the mold cavity and activating the foamable resin composition to cause expansion and generate pressure within the mold cavity and thereby provide intimate bonding of the core to the shell.
