摘要：A method of forming a composite component in which the component comprises a series of sub-layers and in which the sub-layers are offset with respect to one or all of the other sub-layers forming the composite component.

主权项：1. A method of forming a composite component, said component comprising a series of sub-layers together forming a composite stack, each sub-layer comprising a plurality of plies; said method comprising the steps of: selecting a start position for laying up a first sub-layer of plies;laying-up from said position four or more plies to form a first sub-layer; and laying-up a plurality of subsequent sub-layers of four or more plies each layed-up on top of a preceding sub-layer;wherein the start position for laying-up each subsequent sub-layer is selected so as to be displaced laterally with respect to the start position of the preceding sublayer; andfurther wherein the lay-up start position of the first sub-layer defines a datum extending through each of the four or more plies in each of the sub-layers from the first to the final sub-layer of the composite stack and wherein the lay-up start position of each subsequent sub-layer is displaced so as to alternate between each side of said datum.
