A cargo beam assembly (100) for an aircraft including a carbon fiber reinforced polymer (CFRP) cargo beam (10) and a plurality of CFRP stanchions (20) and CFRP c-splice plates (30) each connected to the CFRP cargo beam by overlapping CFRP plies. The flanges of the cargo beam assembly may all be facing a single direction. The components of the assembly may all be formed with CFRP plies configured in a traditional and non-traditional layup. The CFRP stanchions and CFRP c-splice plates are configured to connect the cargo beam assembly to a keel frame (280) of an aircraft. The upper flange (11) of the CFRP cargo beam may include a pad up (15) above each CFRP stanchion connected to the CFRP cargo beam. The interface between each CFRP stanchion and the CFRP cargo beam may be a flange radius that includes a ramped pad up. Darting may provide load transfer between a CFRP stanchion and the CFRP cargo beam.
