An aerofoil component (25) is formed of continuous fibre-reinforced polymer composite created by curing laid up pre-preg layers extending in radial and chordal directions of the aerofoil component. The aerofoil component further includes a plurality of Z-pins extending across the layers of the aerofoil component to pin the layers together. The Z-pins are arranged in a pattern forming a chevron (39) on the pressure and/or suction surface (31) of the aerofoil component, the chevron having a vertex and two arms extending at an angle from each other away from the vertex. The chevron is pointed either (i) towards the radially inner root of the aerofoil component (25) such that one of the arms extends radially outwardly from the vertex towards a leading edge (50) of the aerofoil component, and the other arm extends radially outwardly from the vertex towards a trailing edge (52) of the aerofoil component, or (ii) towards the radially outer tip of the aerofoil component such that one of the arms extends radially inwardly from the vertex towards a trailing edge (52) of the aerofoil component, and the other arm extends radially inwardly from the vertex towards a leading edge (50) of the aerofoil component (25).
