Advantages of a Chem-milled / Unistructure Product
 |
Integral reinforcement is more weight efficient. 1. Overlapping skin and stiffener combinations introduce additional weight. 2. Tight radii naturally produced by the chem-milled product cannot be cost-effectively machined. Load paths are continuous. 1. Integral rib construction allows smooth load transfer across the structure. 2. Global and local rib tailoring is utilized to reduce stress concentrations. Natural chem-mill radius provides structural benefits. 1. Stress risers are reduced or eliminated. 2. Local panel sections have increased stability. Maintenance and reliability are improved. 1. Rivet construction quality and structural negatives are eliminated. 2. Piece part count is reduced. 3. No wear links or bond lines. |
