A composite aerofoil assembly and a composite dovetail portion are disclosed. The aerofoil and dovetail 112 comprise a core 130, a first set of plies 134, and a second set of plies 136. The core 130 being formed of multiple composite plies. The first set of plies 134 being formed of multiple unidirectional plies. The second set of plies 136 having a radially outermost ply with at least two fibres that are either braided or woven. One of the fibres of the outer plies 136 has an orientation of 0o. The aerofoil may be used in the fan section of a turbine engine. The dovetail portion is designed to withstand high mechanical stresses associated with the operation of the turbine engine.
