Stiff Composite Structures - Patent 6730382

A damage-resistant structure suitable for ship's stanchions and other tube and post applications that are susceptible to permanent bending deformation from impacts or overloads is revealed. Multiple stiff, strong, axially oriented high aspect ratio reinforcements, in the form of fibers and/or prefabricated composite or metal parts, are arranged parallel to the main axis of the structural tube. A high strain-to-failure matrix material positions, supports and, in some cases, also encapsulates the prefabricated axial reinforcing materials. The axial reinforcements provide the required strength and stiffness properties of the overall structure, while the more resilient unreinforced or lightly reinforced high strain matrix of the global structure provides the assembly with the ability to undergo large elastic buckling.
