A composite component, such as an aerofoil component for a gas turbine engine, comprises a body and a platform which are formed from respective body (6) and platform (18,20) preforms. The body preform (6) includes fibres (13) which are directed laterally of the preform, forming a cavity (16) in the end of the preform (6). The platform preform (18) includes a projection (24) constituting a deltoid filler which is received in the cavity (16). The projection (24) includes a 3D woven structure of reinforcement fibres so that the cavity (16) is occupied by fibres to give the platform a generally uniform volume fraction. A further platform preform (20) fits over the body preform (6) so that the lateral fibres (13) are sandwiched between the platform preforms (18,20). |
