Patent number: 8404311Abstract: A resin composition that is storable at ambient temperatures. The resin composition forms a cured resin when exposed to a curing agent and heated to a curing temperature that is relatively close to ambient temperature. The resin composition includes a resin component that is composed of a liquid part that is made up of one or more liquid thermosetting resins and a solid part that includes particles of one or more solid thermosetting resins. The liquid part further includes a gelation agent that is present in a sufficient amount to maintain the particles in suspension within the liquid part at ambient temperatures. The viscosity of the resin component changes from a high viscosity state to a low viscosity state when the temperature is increased from ambient temperature to the curing temperature. The high viscosity state is substantially more viscous than the low viscosity state.Type: GrantFiled: November 8, 2011Date of Patent: March 26, 2013Assignee: Hexcel Composites, Ltd.Inventors: Chris Harrington, Philip C.

Patent number: 8304080Abstract: A resin composition that is storable at ambient temperatures. The resin composition forms a cured resin when exposed to a curing agent and heated to a curing temperature that is relatively close to ambient temperature. The resin composition includes a crystalline resin component that is sandwiched between two non-crystalline resin components to provide a zone that is rich in crystalline thermosetting resin. The crystalline thermosetting resin has a melting point that is above ambient temperature, but below the curing temperature. The viscosity of the resin component changes from a high viscosity state to a low viscosity state when the temperature is increased from ambient temperature to the curing temperature.Type: GrantFiled: November 23, 2010Date of Patent: November 6, 2012Assignee: Hexcel Composites Ltd.Inventors: Chris Harrington, Philip C.

Patent number: 7255549Abstract: The flow of resin during the molding of composite articles is controlled by forming areas of immobilized resin during the infusion of resin into the fibrous body. The immobilized resin is formed using an immobilization agent that interacts with the infused resin to form a high viscosity resin barrier that is effective in blocking the flow of non-immobilized resin. The barriers of immobilized resin are located within the fibrous body so as to control the flow of non-immobilized resin during the molding process to prevent or least reduce resin depletion and to selectively block resin flow from the mold.Type: GrantFiled: December 10, 2003Date of Patent: August 14, 2007Assignee: Hexcel Composites, Ltd.Inventor: Philip C.
