Do you have a design that needs increased panel stiffness? Are you looking to increase the structural performance of our carbon fiber sheets? Solve your problems with DragonPlate's carbon fiber hat stiffeners. They can easily be incorporated into existing designs to increase the structural performance by adding stiffness.
Our carbon fiber hat stiffeners are comprised of plain weave carbon fiber in both 0°/90° and ±45° orientations, with 0° uni-directional carbon fiber to add stiffness and strength along the length of the hat stiffener. To optimize the design, we have added the unidirectional only to the cap of the hat stiffener. This fiber placement lets us create a stronger and stiffer hat stiffener while minimizing hat stiffener weight. This design creates a high stiffness to weight ratio, and also creates a beam that is more torsionally rigid when bonded than an i-beam. The carbon fiber hat stiffener has a textured finish on the outside and on the flange surfaces to create an ideal bonding surface.
