HAECO turned to TeXtreme® to help optimize their current seat design for weight, while still maintaining mechanical properties. TeXtreme® used calculation, simulation and manufacturing support to help HAECO reduce the weight of the aircraft seat by almost 20%. TeXtreme® wisely optimized the composite lay-up. Also, the TeXtreme® fabric has been judiciously used so that its specific architecture could help for a better bearing performance and resistance to cracks propagation. Not only has TeXtreme® achieved a significant weight reduction while maintaining the desired stiffness but it has also contributed to save some manufacturing labor by decreasing the number of patches used.
