Abstract: There is disclosed a method of manufacturing a composite component, the method comprising laying-up a plurality of successive plies of composite material to produce a pre-form (12) for the component in a lay-up procedure, wherein a portion of each ply of composite material is heated to at least a threshold temperature of 45° C. during a period of the lay-up procedure.

Abstract: There is disclosed a method of designing a plybook (204, 708) for a composite component (402), comprising: defining a component volume (12) corresponding to the composite component (402) to be manufactured; defining a plurality of successive plies (20) of composite material to fill the component volume (12); simulating at least some of the plurality of successive plies (20) of composite material based on an estimate of variable cured ply thickness, wherein the variable cured ply thickness is estimated by: simulating at least a portion of a respective ply (20) of composite material; and estimating a cured ply thickness for the portion of composite material at least partly based on local conditions of the portion. A plybook (204, 708) is defined based on the plurality of simulated plies (20).
