Patents by Inventor James F. Pratte

James F. Pratte 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).

  • Thermoplastic composites and methods of making and using same
    Patent number: 9550330
    Abstract: A plurality of thermoplastic composite structures are laminated to each other in a lay-up arrangement to form a laminate. Each thermoplastic composite structure is composed of a core composite layer and a surface layer polymer applied to opposing surfaces of the core composite layer. The core composite layer is composed of a fibrous substrate and one or more high performance polymers, which crystallize at a faster rate than the surface layer polymer.
    Type: Grant
    Filed: March 6, 2012
    Date of Patent: January 24, 2017
    Assignee: Cytec Technology Corp.
    Inventors: James F. Pratte, Scott A. Rogers, Dominique Ponsolle

  • Thermoplastic Composites and Methods of Making and Using Same
    Publication number: 20110097575
    Abstract: Thermoplastic composites having a core composite layer including a fibrous substrate and one or more high performance polymer, and a surface layer polymer applied to at least one surface of the core composite layer, which forms a polymer blend with the high performance polymer thereby imparting improved toughness and processing times, and methods for making and using same, are provided herein.

  • Polyimides having high Tg, high TOS, and low moisture regain
    Patent number: 6127509
    Abstract: Polyimide polymers from 3,4,3',4'-biphenyltetracarboxylic dianhydride and 3,4,3',4'-benzophenonetetracarboxylic dianhydride and a diamine such as p-phenylenediamine exhibit a high glass transition temperature, high thermal oxidative stability and low moisture regain, useful for structural applications.
