COMPOSITE BEAM CHORD BETWEEN REINFORCEMENT PLATES AND RELATED METHOD OF MANUFACTURING

摘要

A composite beam chord (7) is between first and second reinforcement plates (8, 9). The beam chord (7) includes a first ply of reinforcing fibers with a fiber orientation of +a (degrees with respect to a longitudinal axis of the beam chord (7) and a second ply of reinforcing fibers with a fiber orientation of - a degrees with respect to the longitudinal axis. The angle a is between 2 and 12 degrees for suppression or delay of ply splitting.
