  • Composite materials with improved performance
    Patent number: 7972686
    Abstract: A composite material comprising at least one polymeric resin and optionally at least one fibrous reinforcement, where the polymeric resin comprises; at least one difunctional epoxy resin; and at least one epoxy resin with a functionality greater than two having at least one meta-substituted phenyl ring in its backbone.
    Type: Grant
    Filed: October 2, 2007
    Date of Patent: July 5, 2011
    Assignees: Hexcel Composites, Ltd., Hexcel Corporation
    Inventors: David Tilbrook, Dana Blair, Maureen Boyle, Paul Mackenzie
  • Pre-impregnated composite materials with improved performance
    Patent number: 7968179
    Abstract: Pre-impregnated composite material (prepreg) is provided that can be molded to form composite parts that have high levels of both strength and damage tolerance without causing any substantial negative impact upon the physical or chemical characteristics of the uncured prepreg or cured part. This is achieved by including in the matrix resin a substantial amount of a multifunctional aromatic epoxy resin that has at least one phenyl group that is meta-substituted.

  • Pigmented panel assembly
    Patent number: 7112372
    Abstract: Panel assemblies that include a core sandwiched between face sheets made from composite material. A pigmented topcoat layer is applied directly to the composite material without the need for a separate adhesive. The pigmented topcoat layer includes a thermoplastic binder resin/pigment mixture that can be cured with the composite material in a single step. The topcoat may include permanent and/or temporary substrates for carrying the binder resin/pigment mixture and for providing a surface finish to the panel assembly.
