ABSTRACT:
A climbing device for a tree or other vertical columnar member having a platform fashioned from fiber-reinforced composite material. The platform is a one-piece structure having a peripheral skin with bi-directionally oriented reinforcing fibers and longitudinally extending reinforcing fibers. The back bar is also fashioned from fiber-reinforced composite material having a peripheral skin with bi-directionally oriented reinforcing fibers and longitudinally extending reinforcing fibers. Fiber-reinforced members include a foam core for shape retention. The manufacturing process permits use of T-shaped joints in fiber-reinforced structures.
