    摘要： A method of through-thickness reinforcing a laminated material (100) is disclosed, in which a reinforcing element (240) is coated with a thermoplastic layer (250). The reinforcing element is inserted into a base material, and a matrix material (230), such as a polymeric, is included in the base material. The combination is then cured, or heated, such that the thermoplastic layer and the matrix material diffuse into each other, thereby forming an interphase region (260) around the reinforcing element. This interphase region helps to prevent cracks from propagating from the reinforcing element.

    摘要： A retainer plate (44) is provided for retaining a dovetail root (36) of a fan blade (34) of a gas turbine engine in a corresponding axially-extending slot in the rim (38) of a fan disc (32). The plate locates in a cavity formed at an end of the slot such that a first side (52) of the plate is arranged for contact with an axial end face of the dovetail root and an opposite second side (54) of the plate is arranged for contact with an abutment surface of the cavity to limit axial movement of the root along the slot. The retainer plate (44) is a unitary component and has a layered structure including a first layer (56) at the first side of the plate, a second layer (58) at the second side of the plate, and an intermediate layer (60) between the first and the second layers. The first, intermediate and second layers are formed of different materials. The Young's moduli of the first and intermediate layers in the axial direction are less than that of the second layer. A fan assembly including the retainer plate and a gas turbine engine having the fan assembly.
