• Composite technology developments

    The art of black magic

    The demonstrators showcased in this page reveal some of the details of the technology developments we've been part of. The two pictures seen on the left correspond to the development of spacecraft central cylinders and launcher interstages featuring composite lattice and grid-stiffened architectures respectively.


    We have developed and patented a manufacturing technology for unidirectional pre-preg grid-stiffened and lattice composite structures for application in the space, aviation and industrial domains.

     

    Grid-stiffened launcher structures technology demonstrator.

    Our technology enables optimally tailored load paths and attachment points using a cost effective one-shot manufacturing method leading to unprecedented high-quality specific stiffness and strength, low-cost and low lead time products.

     

    We're equally at home getting you a solution to your particular technology or product challenge. Specifically for composite structures ATG SpaceLabs has extensive expertise in:
