ABSTRACT:
In bending rods reinforced with continuous fibers, buckling or stretching of reinforcing fibers is reduced by conforming the continuous fibers to a helical configuration within the rods before or when the rods are bent. The helical configuration causes fibers near the surface of the rod to travel substantially the same distance when the rod is bent whether the fibers are on the inside radius or the outside radius of the bend.
