1. A method of fabricating a plurality of composite stringers, the method comprising:
forming a plurality of pre-cured composite stringers on a forming device, the pre-cured composite stringers comprising different hat portions having different cross-section shapes; and
transferring each of the pre-cured composite stringers from the forming device to a post-forming processing device, comprising:
a base, comprising a channel, and
a support structure, at least partially extending within the channel and along a length of the channel and conforming to each hat portion and being reshaped for each different cross-section shape of each hat portion, wherein the support structure is attached to the base at side walls of the channel.
