Phil H. Cook has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Process for resin transfer molding
    Patent number: 5721051
    Abstract: An improved process to make composites contains the steps of: (1) partially curing a tackifier resin in contact with a substrate to form a shapeable preform; (2) adding a matrix resin and co-curing the tackifier and matrix resin to form a composite. The resulting composites are useful in structural applications.
    Type: Grant
    Filed: April 22, 1996
    Date of Patent: February 24, 1998
    Assignee: The Dow Chemical Company
    Inventors: Warren D. White, Phil H. Cook, Martin Wai, William Davis
  • Process for resin transfer molding and preform used in the process
    Patent number: 5427725

  • Process for resin transfer molding using a partially cured tackifier
    Patent number: 5427726
    Abstract: An improved process to make composites contains the steps of: (1) contacting a substrate with a thermoplastic partially-cured curable resin at above the glass-transition temperature to form a preform; (2) adding a matrix resin that can dissolve the tackifier and co-curing the tackifier and matrix resin to form a composite. The resulting composites are useful in structural applications.
