Abstract: Methods of designing a plybook for a composite component are disclosed. Included method comprising: defining a component volume corresponding to the composite component to be manufactured; defining a plurality of successive plies of composite material to fill the component volume; simulating at least some of the plurality of successive plies 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 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 is defined based on the plurality of simulated plies.

Abstract: A composite component having a body formed from a plurality of fiber reinforced non-metallic layers. The body includes a delamination region configured so as to permit delamination; and a deflector region configured so as to resist delamination. In the event of delamination, delamination is deflected to and continues to propagate in the delamination region.

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).
