    摘要: A thrust reverser cascade of an aircraft engine comprises a frame and a vane overmolded onto the frame. The frame and the vane each comprise reinforcement fibers in a thermoplastic matrix. A method is disclosed for manufacturing the thrust reverser cascade or another part comprising an aerodynamic surface configured to interact with a flow of fluid. The method comprises providing a first portion of the part and overmolding a second portion of the part onto the first portion where the second portion includes the aerodynamic surface.

    摘要: 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.
