Composite beam chord between reinforcement plates

摘要

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