AIRFOIL FOR A GAS TURBINE ENGINE WITH TUBES AND SERPENTINE FIBER PLY LAYUP
An airfoil (60) includes an airfoil section (64) that is formed of a fiber-reinforced composite that has fiber plies (72). The fiber plies (72) include at least one overwrap fiber ply (74), first and second support fiber plies (76), and a serpentine fiber ply (78). The overwrap fiber ply (74) circumscribes an internal cavity (70) and defines first and second sides (64c, 64d) and leading and trailing ends (64a, 64b) of the airfoil section (64). The first and second support fiber plies (76) define respective first and second radial tubes (76a, 76b) in the internal cavity (70). The serpentine fiber ply (78) winds from the first side (64c) and around the first radial tube (76a) to the second side (64d), then from the second side (64d) back to the first side (64c), and then from the first side (64c) and around the second radial tube (76b) back to the second side (64d).
