A process for inhibiting delamination in a bend of a component formed of a continuous fiber-reinforced composite material having layers containing arrays of unidirectional fibrous elements in a matrix material. A preform of the component is formed by laying-up prepreg tapes corresponding to layers of the component. Each tape contains a matrix precursor, a binder, and an array of the fibrous elements. The tapes are laid-up so that the fibrous elements of at least a first tape traverse the bend, and the fibrous elements lie in planes that are not perpendicular to the axis of curvature of the bend. The preform then undergoes thermal processing, during which delamination of the layers in the bend is inhibited as a result of none of the fibrous elements lying in a plane perpendicular to the axis of curvature of the bend.
