Case story

Space Without The Weight - Grid Stiffened and Lattice Composite Structure

ATG Europe has recently developed a patented manufacturing process that enables significant mass and cost savings for space and launch vehicle applications. Utilizing uni-directional prepregs from Toray Advanced Composites, the grid-stiffened and lattice composite structure is comprised of continuous carbon fiber tows arranged in an overlapping lattice fashion.

The application of this architecture can positively impact multiple applications e.g., spacecraft central cylinders—the core component of a satellite’s structure. The structure was manufactured using the Toray Advanced Composites RS-36 epoxy prepreg system, with Toray M55J high modulus fiber as a unidirectional reinforcement. Established as a material for space applications, this resulted in an impressive performance whilst also ensuring the required material outgassing characteristics for the component.

GRID-STIFFENED AND LATTICE ARCHITECTURE BENEFITS

  • High performing and extremely lightweight
  • Provides up to 30% mass reduction compared to sandwich structures
  • Reduces part cost by 30%
