Patent number: 10695985Abstract: A method for inserting an insert into a hole in a composite material made from a plurality of carbon fiber layers suspended in a resin material includes lowering a temperature of the insert to a reduced temperature at which a coefficient of thermal expansion of a material of the insert causes the insert to contract to a first perimeter, inserting the insert at the reduced temperature into the hole, and permitting the temperature of the insert to increase from the reduced temperature to an operational temperature. At the operational temperature, the insert expands to a second perimeter so that the insert is retained within the composite material due to an interference between the insert and the composite material. The interference transfers a structural load from the insert to the composite material and results in damage to the composite material if the insert is dislodged at the operational temperature.Type: GrantFiled: September 9, 2016Date of Patent: June 30, 2020Assignee: SHORT BROTHERS PLCInventors: Samuel Colin Hanna, Robert Samuel Wilson, William Christopher Campbell

Patent number: 8795578Abstract: A method and apparatus for forming a fiber reinforced composite structure comprising at least two components, a hard base tool presenting a first tool face, a second tooling element presenting a second tool face to locate the second component against the first component. Components are of a dry fibrous form and are to be injected with a liquid resin. A flexible bagging blanket forms with the tools a sealed enclosure into which the resin is injected to form the structure by resin transfer infusion. To maintain the relative dispositions of the components without the need for elaborate mandrel plates, control rods are inserted at least partially through the two components to act as fasteners and to maintain the relative disposition of the components during resin injection. After injection the assembly is cured and the control rods may remain in situ or be removed from the structure.Type: GrantFiled: July 19, 2007Date of Patent: August 5, 2014Assignee: Short Brothers PLCInventors: William James Trevor Millar, Robert Samuel Wilson, Jonathan James McConnell
